Hi readers, I hope you are all well. In this post, we discuss the main topic, equilibrium. Equilibrium can play a fundamental role in the modern and different fields of science. In physics, engineering, or also in chemistry the concept of equilibrium describes and provides information about forces that can be applied to the system. In physics, the equilibrium describes the balanced forces and the torque that can be acted on the system or the body. if the body is at rest or in a motion state, equilibrium explains and provides information about the forces that can act in both types of situations persons.
Equilibrium plays a vital role in understanding the forces and the torque because equilibrium provides stability to the system, also it stabilizes the person who is in the state of rest or motion because in both conditions forces always act on it, so for their stabilization equilibrium plays an essential role.
In this post, we can discuss the equilibrium definitions, their types, first equilibrium condition, second equilibrium condition, mathematical expressions, their applications, examples, and related phenomena.
Equilibrium can be defined as:
"The state in which the body is in the state of balance, or the body is in the state of motion or rest with uniform velocity and no net change occurs on it."
Simply equilibrium is a state in which the system or the body is at the condition of balance under the action of forces but there is no net change occurring. Every system achieves equilibrium at some conditions because, without an equilibrium state, the system or the object can't do its work properly.
There are two main types of equilibrium which are common and they are given there:
Mechanical equilibrium
Thermal equilibrium
Their description is given there:
Mechanical equilibrium is the main type of equilibrium and it can be defined as:
In the system or an object mechanical equilibrium occurs when there is no force, torque net force, or acceleration acting on the object or the system.
Mechanical equilibrium occurs during the state of motion mostly. Mechanical equilibrium can be divided into two types which are also the main types of equilibrium and they are given below:
Static equilibrium
Dynamic equilibrium
These are the further divisions of the mechanical equilibrium Details are given there:
Static equilibrium can be defined as:
"static equilibrium can achieved by the body when the body is at rest and all forces which can act on the body including torque and acceleration sum is equal to zero."
Dynamic equilibrium can be defined as:
"Dynamic equilibrium can be achieved by the body when the body moves with a constant velocity and the all forces and torque which can be acted on the body their sum is equal to zero.”
Thermal equilibrium can be defined as:
"The two objects or the two or more systems can achieve the state of thermal dynamics when no exothermic or endothermic heat exchange occurs and with some condition or time both systems can be reached to the same temperature."
These are the major types of equilibrium but the types of equilibrium in physics are given there:
The types of equilibrium in physics with their uses and examples are given there:
Dynamic equilibrium
Radiative equilibrium
Thermal equilibrium
Static equilibrium
Chemical equilibrium
Their detailed definitions, mathematical expressions, formulas, and examples are given there:
Dynamic equilibrium can be achieved by the body when the body moves with a constant velocity and all forces and torque which can be acted on the body their sum are equal to zero. In dynamic equilibrium all forces which can be acted on the object are balanced. Mostly dynamic equilibrium can be used to understand or determine the objects that can be moved without acceleration.
As we know in dynamic equilibrium the all forces sum is equal to 0 then it can be written as:
F = 0
Or the sum of torque is also equal to zero, hence it can be written as:
𝛕 = 0
The body or object can be rotated around its axis with uniform angular velocity and no acceleration can be calculated or measured and all sum of forces that can be acted are 0
The car that can be moved with uniform linear velocity on a straight road, and not change their speed then the force which can be acted to maintain the road friction or air friction can be produced through the driving force which can be produced through the engines.
The paratrooper can also fly in the sky due to the dynamic equilibrium which stabilizes them to fly in the sky efficiently.
The airplane can also fly with a state of dynamic equilibrium because it can fly with constant speed and the weight and thrust force can balance the drag force by balancing their forces it can fly efficiently.
Radiative equilibrium is the state that can be achieved by the system or the object by absorbing the radiation or emitting the radiation at the same time and rate through equal emitting and absorbing radiation of the system and the object can achieved the dynamic equilibrium state efficently.
Rate of absorption of radiation = rate of emission of radiation
Stars can also maintain their lifecycle phase by emitting or absorbing radiation and achieving radioactive equilibrium. the stars produce energy through the nuclear fusion reaction and it can also radiate the absorbing energy into space and maintain gain radiative equilibrium.
The temperature or radiation can come from the sun and is maintained in the earth by radiative equilibrium because the earth absorbs all solar radiation and emits infrared radiation on the surface of the earth.
The two objects or two or more systems can achieve the state of thermal dynamics when no exothermic or endothermic heat exchange occurs and with some condition or time, both systems can reach the same temperature. thermal equilibrium concepts are essential in thermodynamics and also in their laws.
The temperature of the object and the system that can achieve the thermal equilibrium can represented through the symbol T.
No heat exchange occurs in the system when they achieve the thermal equilibrium then it can be written as:
T1 = T2 = T3=........ = Tn
For the two metal spoons, one is cold or the other is hot but if we check after some time then it can be observed that both metal spoons have the same temperature because both of them achieve thermal equilibrium.
If we leave the hot cup of tea or coffee in the room or open environment, then after some time we can observe that the hot cup of tea or coffee temperature becomes equal to the room or environment temperature,
Static equilibrium can achieved by the body when the body is at rest and all forces that can act on the body including torque and acceleration sum are equal to zero. In the static equilibrium state, the object always remains at rest so that's why the static equilibrium can be used to determine or understand those objects that can't move and always remain at rest. Simply static means rest so static equilibrium can only achieved by those objects or systems that can't be moved.
As we know in static equilibrium the all forces sum is equal to 0 then it can be written as:
F = 0
F represents the sum of all forces that can be acted on the body or object.
Or the sum of torque is also equal to zero, hence it can be written as:
𝛕 = 0
𝛕 represents the sum of all torques that can be acted on the body or object.
The book can be lying on the table or at rest, then the forces that can be acted on the table are maintained or normalized through the gravitational force that can be acted on the book which is lying on the table
The bridge that can be used for traffic is always in a static state, then it can maintain its static equilibrium by balancing the forces and the weight or load that act on the bridge.
In chemical reactions, chemical equilibrium can be achieved, when the forward and the reverse reaction rates are the same under the same conditions, and when the concentration of the products and the reactants can't be changed during the reaction then this state can be achieved. Mostly in chemistry, the chemical equilibrium can be used to determine or understand the concentration of reaction but in physics sometimes it can be used.
The rate of forward reaction = the rate of reverse reaction
The solution of the salt becomes in the equilibrium or saturation state when the rate of salt dissolution is equal to the rate of precipitation. But if we can provide the temperature to the solution of salt then we can change their equilibrium state also.
When we close the container in which hydrogen iodide solution is present, then this solution can achieve the equilibrium state easily because, in the closed container, we can't change the conditions and can't change the temperature or concentration of the reactant and product amount.
Two main conditions are essential for achieving the equilibrium state. If the object and the system can't follow these two main conditions then it can't achieve the equilibrium state. The two conditions for the equilibrium state are given there:
The first condition of equilibrium ( equilibrium of forces)
A second condition of equilibrium ( equilibrium of torque
in the previous post, we can discuss the first condition of equilibrium and now we can discuss the detail of the second condition of equilibrium.
The second condition of equilibrium can also referred to as the equilibrium of torque. According to the second condition, the all torque that can be acted on the body, their sum is always equal to zero. If the object or system follows this condition then it means that the body can't rotate around its axis and can't do the rotational motion.
The second condition of equilibrium is defined as:
The sum of all vector torque that can be acted on the object or the system is always equal to zero. Because this condition describes that the object or the system can't do the rotational motion around their axis.
𝛕 = 0
𝛕 represented the sum of all torque that can be acted on the body.
As we know the torque is equal to the position vector or the distance from the axis of rotation and the vector product of force F and the sin θ are the angle between the r and f. The it can be mathematically represented as:
𝛕 = r F sin θ
Then if the sum of all torque is equal to zero it proves that the body which can be moved with rotational motion is at the equilibrium state and all forces have become zero and it can be written as:
𝛕 = 0
When all forces that can be acted on the object in one plane or are coplanar then we can apply the condition of equilibrium we stabilized or maintained them.
All forces can be passed through one point which is the line of action and the body moves around into its axis within the line of action.
By choosing the axis we can calculate the torque efficiently and the position of the object and the position of the axis is arbitrary.
The second condition of equilibrium or the equilibrium of forces is essentially used to determine or understand those systems or objects that can do the rotational motion.
This condition is the base in the field of dynamics because in this field we can deal with different types of motion. In mechanics, it can help to analyze the structures and the components that can be used in the designing of the system which can do the rotational motion, and also analyze how they achieve the equilibrium state by balancing the forces and the load which can be acted on them.
The seesaw can pivot in the center. Two children with different weights sit on both sides but they can show the equilibrium state when the torque that can be acted on is equal to zero by balancing the load or forces that can be acted on the swing.
The ladder can stand with the support of the wall. The ladder may fall but if it becomes at the equilibrium state by balancing the forces then it can't fall.
The second condition of equilibrium can follow many different fields of science and it can be used in many different applications that can be used in daily life some explanations are given there:
Every day situations
Structural engineering
Mechanical system
In our daily lives, the second condition of equilibrium can be used to balance or stabilize many different things. All systems can be managed or stabilized due to equilibrium. For instance, the picture can be hung with the hook and the weight of the picture or sign can be balanced through the hook. Torque can also be produced by the picture and it can be balanced by following the second condition of equilibrium.
In the field of engineering, engineers can design or choose the components that can manage the rotational motion with equilibrium and manage all forces or torque that can be acted on it. Engineers always prefer to choose those components that can efficiently work and remain in the equilibrium state. For instance, the cantilever beam can be designed by the engineers, they calculate the all torque that can be acted on it and then also analyze that they can able to bear the load or ensure that the beam is at an equilibrium state or not move around their axis to produced torque.
The second equilibrium can be used in the field of mechanics in which the components are designed to work properly without error. The second condition of equilibrium can also used for checking the proper functioning of the machines and also for their safety and for increasing their efficacy to do work properly. For instance, the gear systems that are used in the vehicles are designed by the engineers, they can be designed by ensuring the components can balance all forces and the torque must be equal to 0.
With time and with the development of modern science and technology equilibrium can be used in many different new topics with new concepts and ideas that can be presented through modern research. Some modern concepts and ideas about the second condition of the equilibrium are given there:
Equilibrium in the quantum system
Metastable equilibrium
Equilibrium in the dynamic systems
The second condition of the equilibrium can also now be used in the quantum system because in the quantum system the probabilities and managed or stabilized efficiently. The superpositions and the quantum tunneling can also be understood or determined through the second condition of the equilibrium. For instance, the electrons that can distributed in the conductors, the energy, and the distribution of the electrons can be managed or stabilized by using or following the conditions of the equilibrium.
The second condition of equilibrium can be used in the metastable, in this, the larger or smaller distribution can be managed or stabilized efficiently. For instance, the pencils that we can use can also be balanced on the tip, but if a small disturbance occurs the pencil can fall and distribute the equilibrium state easily.
In the dynamic system, the equilibrium occurs when it follows the second condition of the equilibrium. If we understand the equilibrium of torque then we can analyze or stabilize all control systems or dynamic systems. For instance, the satellites can be moved around their axis, and in the orbit, their stabilization can be managed by following the second condition. Because the second condition of the equilibrium maintained to move in orbit or doesn't allow them to move irregularly in the other orbits.
The advanced topics in which the second condition of equilibrium is used are given there:
Equilibrium in elastic system
Equilibrium in the three-dimension
Multiple forces equilibrium in the system
Some practical examples in which the second condition of equilibrium is used are given there:
Aerospace engineering
Architectures
Building designs
Robotics
Automotive engineering
The equilibrium of torque, which is also referred to as the second condition of the equilibrium is the essential or fundamental concept in the dynamics or mechanics in which the system and the object can do the rotational motion. If we can apply the second condition of equilibrium we can stabilize the different applications in daily life or mechanics. In the era of the modern sciences, equilibrium is essential in every system for working properly and for better output efficiency. by understanding this article or post or understanding the second condition of equilibrium it is easy to balance the objects in the physical world and also in the major fields of science.

The bridge that can be used for traffic is always in a static state, then it can maintain its static equilibrium by balancing the forces and the weight or load that act on the bridge.
In chemical reactions, chemical equilibrium can be achieved, when the forward and the reverse reaction rates are the same under the same conditions, and when the concentration of the products and the reactants can't be changed during the reaction then this state can be achieved. Mostly in chemistry, the chemical equilibrium can be used to determine or understand the concentration of reaction but in physics sometimes it can be used.

Two main conditions are essential for achieving the equilibrium state. If the object and the system can't follow these two main conditions then it can't achieve the equilibrium state. The two conditions for the equilibrium state are given there:
The first condition of equilibrium ( equilibrium of forces)
A second condition of equilibrium ( equilibrium of torque
Details of the first condition of equilibrium are given there:
The first condition of equilibrium is also known or referred to as the equilibrium of forces because in this condition all forces that act on the body or the object must equal to zero. If the system or the object can't follow this condition then it never can achieve the equilibrium state.
The first condition of equilibrium or the equilibrium of forces can be defined as:
The sum of all vector forces that can act on the object or any system externally is always equal or must equal to zero. Mathematically it can be written as:
F = 0
This equation proves or shows that the sum of all forces is equal to zero so that is why the object that is at rest or motion has not been accelerated because the object is in a uniform state of motion or the rest.
If the system which can follow the first condition of equilibrium to achieve the state of equilibrium can lie in the two dimensions then it can be written as:
Fx = 0
This equation or formula represented the sum of all forces in the x direction.
Fy = 0
This equation or formula represented the sum of all forces in the y direction.
Both equations can be used in the two dimension system. But if we balanced the three-dimensional system then the forces are directed on three axes x, y, and z and it can be written as:
Fx = 0
This equation or formula represented the sum of all forces in the x direction.
Fy = 0
This equation or formula represented the sum of all forces in the y direction.
Fz = 0
This equation or formula represented the sum of all forces in the z-direction.
If the forces that can be acted on the object or system are taken in the right direction then these forces are positive.
If the forces that can be acted on the object or system are taken in the left direction then these forces are positive.
If the forces that can be acted on the object or system are taken in the upward direction then these forces are positive.
If the forces that can be acted on the object or system are taken in the downward direction then these forces are positive.
If the forces that can be acted on the object or system are common in plane then these forces are termed as the coplanar.
All stationary and static systems can be analyzed or understood through the first condition of equilibrium. The branch of mechanics in physics, the concept of equilibrium can be discussed in statics principle in which we can deal with or study the forces that can act on a stationary system or object. The equilibrium of forces is fundamentally used for understanding or analyzing the
Structural analysis
Mechanical analysis or designs
Everyday applications
Every day we can use many different objects in which the equilibrium can be seen. In common conditions like hanging the objects and placing different things one by one or balancing them. In hanging or balancing things can be done by the equilibrium so we can also understand the equilibrium interactions in our daily life.
In engineering or physics, we can understand the structures of the system through which the balance can be maintained like the bridges, roads, and buildings that can carry the load stabilized due to the equilibrium condition by balancing the all forces which can act upon it.
Ensuring the stability of buildings, bridges, and other structures under various loads.
In the field of mechanics, equilibrium conditions can be followed to design the efficient machine or their designs. In designing the machines the components are chosen that can stand with the forces that can act upon it and maintain them efficiently at the rest or in motion also.
The equilibrium in the static sign can be hung on the wall.
Let us consider the sign that we can hang on the wall with two ropes so they have different angles. The angle that can be made by the ropes during hanging is approximately 30° or 45°. The weight of the sign that can be hanged is 100N. Now we can find or determine the tension that can be produced in ropes for balancing the sign on the wall.
Now let the T1 tension for the first rope which can make an angle of 45° and T2 the tension for the second rope which can make an angle of 55°. For achieving the equilibrium state all forces that can act on the sign in the x and y direction, their sum is must be equal to 0.
The forces that can act in the x direction:
T1 cos (30) = T2 cos (45)
The forces which can act on the y direction:
T1 sin ( 30) + T2 sin ( 45) = 100
Now we can solve both of these equations and write as:
T1 cos (30) = T2 cos (45)
T1 32 = T2 12
And then it can be written as:
T1 = T2 23 12
Then,
T1 = T2 26
T1 = T2 23 ……. (i) equation
Now we can solve the equation in which force can be acted in the direction of y and it can be written as;
T1 sin ( 30) + T2 sin ( 45) = 100
T1 12 + T2 22 = 100
Now we can put the value of T1 in the given equation and write it as:
(T2 23 ) 12 + T2 22 = 100
T2 (23 . 12 + 22 ) =100
Then,
T2 ( 22 3 + 22) =100
T2 ( 2 (1 + 3)23) = 100
T2 = 200 32 (1 + 3)
Then,
T2 = 73. 2 N
Equilibrium of forces or the first condition of equilibrium can be used in many different fields because it can help to describe the forces or to maintain the system some applications of equilibrium of forces are given there:
Structural engineering
Everyday situations
Mechanical systems
In the field of engineering, where bridges buildings, and many other machines can be designed their equilibrium of forces is essentially used because it can ensure that the design or the components we can use have the ability to carry the load to maintain their balance. And can't collapse or be destroyed due to the imbalance of force or weight. Engineers study or examine whether the components that they can use are efficient or attain equilibrium efficiently or not.
Example:
The engineer can design the bridge through which the traffic can be passed, they use the best components and materials that can manage the forces carry the load efficiently, and attain the equilibrium state without deforming or collapsing.
Every day we can use many different objects in which the equilibrium can be seen. In common conditions like hanging the objects and placing different things one by one or balancing them. In hanging or balancing things can be done by the equilibrium so we can also understand the equilibrium interactions in our daily life.
Example:
When we hang the pictures or any sign on the wall with ropes then the ropes can manage the tension and all forces that can be acted on them and stabilize them to hang the wall without falling. The all forces which can be acted on the ropes and the sign or picture their sum are always equal to zero. And after neutralizing the forces they can achieve stabilization or equilibrium.
In the field of mechanics, equilibrium conditions can be followed to design the efficient machine or their designs. In designing the machines the components are chosen that can stand with the forces that can act upon it and maintain them efficiently at the rest or in motion also. In the mechanical field, engineers choose the components very precisely to maintain the equilibrium state.
Examples:
When engineers make heavy machines or vehicles like cranes then they check or ensure that the forces that can be acted on the crane arm or the load that can be placed on it are capable of bearing it or not. After ensuring these components' ability they can be allowed to use it or made efficient and heavy machinery.
In the modern era of science and technology, the equilibrium of forces can be used in many new fields according to their need. Some new topics in which the equilibrium of forces can be used are given there:
Equilibrium in elastic system
Equilibrium in three-dimension
Equilibrium in the system with friction
In the elastic system, the equilibrium can be used because when we stretch the spring it can be restored and maintained by balancing the forces that can be acted on it. Equilibrium is essential in all systems and objects because without equilibrium the system can't work properly.
In two dimensions equilibrium can easily attained but now in three dimensions equilibrium must attained by balancing the forces and using the best components in it. For instance, cranes and the tripod or the tables can stand in equilibrium and manage the forces acting upon it in the three dimensions x, y, and z efficiently.
In equilibrium problems, friction can play a vital role. Because when the system interacts with the surface it is obvious that friction can be produced so when we calculate the system's net force for their equilibrium the force of friction can also be calculated because sometimes, friction is the restriction in attaining the equilibrium set. For instance, if we place a block on the surface or the plane then if we want to stabilize the block at the right position it is a must to calculate the all forces that can act on the block along with the force of friction.
Some practical examples in which the equilibrium of forces are commonly used to maintain their work or maintain their output efficiency or control on them are given there:
Robotics
Automotive engineering
Architecture
Building designing
Aerospace engineering
In the era of modern science and technology, the first condition of equilibrium can play a fundamental role in different fields like physics, mechanics, chemicals, or engineering because it can provide basic information and help to understand all static systems and objects efficiently. By understanding this condition of equilibrium we can achieve the system balanced without producing the error or acceleration. Through their application in many new fields, we can easily understand them because this condition of equilibrium can be used in our daily life situations. The equilibrium of forces is easy to understand because in this the sum of forces is always equal to zero or the forces include the normal force, gravitational force, or maybe the frictional force. But with time it can be more commonly used in the field of science. Equilibrium of forces is the fundamental concept in the field of static or dynamics
Hi readers, I hope you are all well. In the previous articles, we discussed different basic physics topics like vectors and others and now we can discuss the major topic torque in this article. Torque can also be called the rotational force or moment of the force. In physics, mechanics, and engineering torque plays a vital role and has a fundamental concept in these fields. Torque is essential to understand or describe the ability of the force of the object to rotate around its axis. The object moves with the linear force but when the object moves around its axis, some pivot point, or the fulcrum with some force then this rotational force of the object is termed as the torque.
The word torque is derived from the Latin word "torquere" which means turning or twisting. Torque describes both magnitude and direction so that is why it is a vector quantity because only vector quantities describe both magnitude and direction. Rotational dynamics The branch of dynamics can be understood through torque because the rotational force of the object is only described through torque. Torque can be represented through the symbol 𝛕. Torque can also be represented through the M. Now we can start our detailed discussion about torque, its definition, relation with other quantities, their mathematical expression, significance, applications, examples, and many other phenomena.
The idea and concept of the torque was presented by the Archimedes. The use of the lever instrument was studied by the Archmedies and when they studied them then the idea of torques was first described by him. But the term or word torque was first advised by the great scientist James Thomson. Then the experiment was done by scientist P. Thompson in the same year when the idea was described and the experiment was written in the Dynomo electric machinery book in their first edition in the 18th century, 1884.
After this, the great and famous scientist Newton can present or describe the force through which the body moves. So according to their definition when the linear force acts on the moving object and any twist occurs around their axis and changes the force of the body from linear to rotation then it is termed as the torque. For instance, the screwdriver always rotates around its axis As another example of torque the seesaw swing which can be off and on on the groping due to the imbalance of the torque.
Now torque can be used or referred to in many different fields of science to understand the rotation force of a body at the given pivot point or around its axis. Mainly the concept of the moment of force can be described in the early 18th century in 1811, but it can print in the late 18th century and the then torque is also referred to as the moment of force, and the rotational force.
Torque can be defined as:
"the body which can move around their axis with the turning force which can be produced by the body is known as torque."
Torque can also defined as:
The magnitude of the perpendicular distance of the body from the axis of the rotation or the magnitude of the force, product of these both magnitudes are termed as the torque or moment of force:
The torque of the moment of force can also be defined as:
"the cross or the vector product of the radius or the position vector r and the vector force F".
Torque can be written in mathematical form as:
𝛕 = r F
There,
𝛕 represented the torque and the magnitude of the torque was represented through 𝛕.
r represented the position vector and the magnitude of the position vector is represented through the r. position vector is the distance which can be measured by the torque through the point where the force is applied to the axis of rotation.
F represents the force and the magnitude of the force is represented through the F.and the force is perpendicular to the position vector r and represented by the symbol ⊥ .
The magnitude of the torque can be written as:
𝛕 = r F sin
There,
𝛕 denotes the magnitude of the torque.
r denotes the magnitude of the position vector.
denotes the cross or the vector product between the two vectors
F denotes the magnitude of the force.
θ is the angle that is present between the position vector and the force, both of these are the vector quantities.
The direction of the torque can be represented or described through the right-hand rule. Because this rule can efficiently represent the direction of both of these vectors r and the F. According to the right-hand rule, the thumb can represent the torque 𝛕 which is the product of two different vector quantities, then the fingers of the right hand represent the direction of the position vector r and the curl fingers represent the direction of force F.
Torque can depend on the two major factors which are given there:
Moment arm
Magnitude of the force
Both of these factors are the major factors that can directly affect the torque. The moment arm is simply defined as the perpendicular distance of the body from the line of action to the axis of rotation. And these measurements of the moment arm with the force are simply termed the torque.
The torque can show the relationship with many other physical quantities like power, angular momentum, and energy. Mathematical derivation which can show the relationship of torque with other quantities in detail is given there:
The term torque can also be described or understood by using the law of conservation of energy. Because when the body moves with some force then it can cover some distance so they are the mechanical work that can be done by the body. In the angular displacement when the torque acts then the body is in the condition of doing work. The turning force acts on the body around its axis which is fixed with the center of mass so that's why mathematically work with torque can be expressed or written as:
W = θ1θ2 𝛕 d θ
There,
W represented the work that is done by torque.
𝛕 represents the torque through work that can be done
d is the angular displacement in which the torque or turning force can be acted
θ1 or they θ2 are the angle between the initial angular displacement point to the final angular displacement point.
Work energy principal:
The torque can show the relation with the energy or the work according to tyo the work-energy principle in which the work or energy can be changed into rotational kinetic energy on the body and it can be represented or written as:
Er = 12 I ω2
There,
Er represent the rotational kinetic energy
I represented the inertia of the body
ω2represented the angular speed of the body through which they can cover the angular momentum.
Power can also defined in the form of energy or work with unit joule. but the relation of the power with torque is the work that can be done in the unit of time and it can be written as:
P = 𝛕 ω
There,
P represents power.
𝛕 represents the torque.
ω represents the angular velocity through which the body does work.
represented the dot or the scalar product between the two vector quantities torque and angular velocity.
According to this mathematical expression or equation, it can be shown that the torque and the angular velocity scalar or dot product can give the output of the power. the torque in the relationship of the power was dependent upon the angular velocity or the speed. But the torque does not depend on the velocity decreased or maybe increased but it only depends upon the angular velocity. The force also depends upon the velocity of the object on the acceleration or the speed.
The work that can be done on the body when the random variable force acts on the body in the liner displacement or the force which can act on the body with the respect of elemental displacement then it can be written as:
W = s1s2 F . ds ……. (i) equation
There,
S1 and S2 are the initial and the final linear displacements that can be covered by the object during the work.
F represented the force
ds represented the elemental linear displacement.
So,
The elemental displacement ds are also equal to the cross or vector product of the radius and the angular displacement and written as:
ds = d θ r
There,
r represented the radius
d θ represented the angular momentum
Now put the value of the ds in the equation (i)
W = s1s2 F . d θ r
Now as shown in the equation the triple scalar product integers are shown and it can be also written as:
F . d θ r = F r . d θ
If we know that the radius or the angular momentum with force is equal to the torque then it can be written as:
W = s1s2 𝛕. d θ
But if both quantities, torque and angular momentum can lie in the same direction then the angle between them is cos, and their magnitude can be written as the:
= 𝛕. d θ
= r . d θ cos0
= 𝛕 d θ
Then it can be written as:
W = s1s2 𝛕 d θ
Angular momentum which can be acted on the body can be determined through the torque that can act on it and it can be written as:
𝛕 = dLdt
There,
𝛕 represented the torque
L represents the angular momentum
And the t represented the time with the displacement.
Or the angular momentum is also equal to the inertia of the moment and the angular speed and it can be written as:
L = I ω
I represented the moment of inertia and the w represented the angular speed.
And the moment of inertia I is also equal or written as:
I = m r2
Then the total net torque can be written as:
𝛕net = I1w1e1 + I2w2e2 + I3w3e3 + I1w1 de1dt + I2w2 de2dt + I3w3de3dt
𝛕net= Iw + w (Iw)
Then it can also be written as:
deidt = w ei
This equation can be used for newtons law but in some problems, there are only inertia and angular momentum then in a simple way, we can write them as the:
𝛕 = I a
There,
𝛕 represented the torque, I represented the inertia, and the a = w represented the angular velocity or the speed.
This equation can also be called the Newton's second law.
Simply, the angular momentum for a single particle can be defined or written as:
L = r p
There,
L represented the angular momentum of the single particle
r represented the position vector
p represented the linear momentum of the single particle.
But when we can write the angular momentum for time then mathematically it can be written as:
dLdt = dpdt r + drdt p
As shown in the given mathematical equation when we can split the equation into its components and then we can use the product rule of vector because the force is represented the rate of change in the momentumdpdt and the drdt change in the position of the quantity is represented through the velocity symbol v. then it can be written as:
dLdt= F r + v p
There,
V represented the velocity and the F represented the force. Now as shown in the given equation both vector quantities velocity v and the angular momentum p are parallel to each other so they are equal to zero 0 and it can be written as:
dLdt= F r
Now as shown in the given mathematical equation force and the position vector are equal to the torque and when we apply the Newton law then it can be written as:
𝛕net = dLdt= F r
Now through this equation, it can be proved that the torque has a significant relationship with the angular momentum of the single particle. This mathematical equation is the generalized proof of the torque and the angular momentum along the mass.
The units, symbols, and the dimensions of the torque are given there:
For the quantity torque, many units can be used but some major units that can used to express the torque are given there:
Nm ( newton meter)
Dyn . cm ( dyne - centimeter) This unit can be used in the CSG system to express the torque.
Pound foot represented by ( Ibf- ft)
Pound inch, this unit can be used to measure the small torque measurements and represented by ( Ibf- in).
Foot-pound can be represented through Ib- ft.
Like the foot-pound, the torque can also be represented through inch-pound and represented through the in-Ib.
The SI unit of the torque can be written as:
kg . m2 . s-2 ( kilogram meter square per second square)
Dimension of the unit torque is written as:
ML2T-2
Torque can be calculated and depends upon some major factors but some major formulas that are used to calculate the torque for the single force and for the multiple force are given there:
When a single force applies or acts on the body with some distance from their fixed axis of rotation, and the force that acts on the body is perpendicular to the position vector r, then the torque can be written as:
𝛕 = r F
But if the force is not perpendicular to the position vector r then it can be written as:
𝛕 = r F sin θ
there,
θ can represent the angle between the force and the position vector.
When the multiple forces act on the body or object then the torque can be calculated through their vector sum and written as:
𝛕net = 𝛕i
There,
𝛕net represented the total sum of the torque that can act on the body with multiple forces.
and,
𝛕i = ri Fi
Now we can calculate the torque that can act on the rigid body.
As shown in the figure, let us consider the rigid body. According to this figure, the force F acts on the object at the point p, r is the position vector according to the point p, and the angle between the force and the position vector r is represented through the Now we can calculate their torque by their resolution.
In the above figure, we can see the components of the vector according to the rectangular components and then it can be written as:
F cos θ = this is the component of the force in the rectangular component which can act in the direction of the position vector r.
F sin θ = this is the component of the force in the rectangular component which can be perpendicular to the position vector r.
As shown in the above equation, the F cos θ and their line of action can pass through the point O, and this rectangular component due to the line of action becomes zero 0. So that is why the force that can be acted on the body is equal to the F sin θ which can produce the torque and it can be written as:
𝛕 = r( F sin θ)
𝛕 = r F sin θ
Or when we can write with their magnitude or in vector form then it is as:
𝛕 = r F sin θ n
Also, it can be written as:
𝛕 = r F
After the component of force then we can write the rectangular component of the position vector r. It can be written there as:
r cos θ = the component of the position vector r along with the direction of the force.
r sin θ = the component of the position vector r perpendicular to the vector force F.
When the torque is produced due to the force, in this case, we can write the torque as:
𝛕 = l F
there,
L is equal to the moment arm and it can be written as:
l = moment arm = r sin θ
So it can be written as
𝛕 = ( r sin θ) F
𝛕 = r F sin θ
In the magnitude of the vector form it can be written as:
𝛕 = r F sin θ n
Also, it can be written as:
𝛕 = r F
A wrench ( spanner) is used to tighten the nut. The spanner moves around its axis of rotation with some force so it can produce the torque.
The swing seesaw can move up and down on the ground due to the imbalance of the torque because its center is fixed so it can move at the line of action and produce the imbalance torque.
For the rotational motion of the body, torque is the major or counterpart of the force that can act on the moving object.
The body can be moved through the linear motion and the angular motion in which force can be acted, the force is the same as the torque.
The linear acceleration can be described or determined through force and the angular acceleration can be determined or described through the torque.
The torque will be positive if the rotational motion of the object occurs in the anti-clockwise direction, and the torque will be negative if the rotational motion of the object occurs in the clockwise direction.
Torque can play a very fundamental role in many different fields some of their applications in different fields with detail are given there:
Robotics
Mechanical system
Sports and biomechanics
Structural engineering
Their detail is given there:
Torque plays a vital role in the robotic system. Because by the help or understanding of the torque the movement of the robots through their arms or joints is controlled efficiently. Torque helps to determine or describe the force that can act on the joints of the robot through which they can do rotational motion and help to control all movements of the robots precisely or efficiently.
Actuators: actuators are the systems in the robots that can convert the energy to the motion through which the robots can be moved. The functions of the robots are controlled efficiently through the torque. Torque also helps to choose the best and appropriate systems and actuators for making the robotic system accurate or precise.
Robotic arm: the joints are moved through the rotational force which is torque so that's why all joints or arms of the robot have some specific torque value through which they can move or complete their specific movement efficiently.
In the field of mechanics which is the branch of physics, torque are fundamental concept for designing engines or gears, and turbines or generators. Because in these given systems the engines can work with some force which is termed as torque and it can be moved or run through the rotational motion, the efficacy and the output of these systems can be measured also through torque.
Gear system: the efficient and precise gear system can be designed by determining the torque because the torque can be transmitted to the near components through which the system can run efficiently.
Engines: in the mechanical system the engine's efficiency and ability can be determined through the torque. Because the torque describes the ability and the capacity of the engine's acceleration and the capacity to carry the load. So to make efficient and design efficient engines torque can be used.
Torque can play an essential role or help to determine or analyze the movements of the human joints because the joints can do rotational motion. Through torque athletic performance can also be improved or managed. Torque also helps to understand which muscles can apply the force on the joint to do movements and through which muscle we can control the movement and prevent injury chances.
Injury prevention: by understanding the torque detail we can design the many equipment that can help to decrease the risk of injury and also prevent the human or athlete from injury. Torque also helps to understand which muscles can apply the force on the joint to do movements and through which muscle we can control the movement and prevent injury chances.
Athletic performance: the torque is produced by the muscle and these forces act on the joint through the movements that occur, by understanding the muscles that produce torque helps to improve performance, and with training the athlete can maintain or improve their skills efficiently.
The structure stability and the system ability can be determined through the torque. In structural engineering, bridges, buildings, and other designs are made after understanding the torque because it can help to understand the ability of the object to carry the load.
Bridges: when the engineers are designed to make the bridges they determine the torque because it can help them to find or observe whether the bridges can carry the load and are safe to use or not.
Torque can be used in many different advanced topics because the concept of torque can be presented in the 18th century and with time it can be used in many different fields some are given there:

Torque plays a vital role in different fields of science. Torque made the relationship and described the relationship between the linear motion and the rotational motion efficiently. Through understanding the torque we can also understand how the force acts on the body and how the object can be moved around its axis and do the rotational motion efficiently. Torque can be used in our daily life when we used the screw gauge, wrench, and others then they do the rotational motion and produced the torque efficiently. In the era of modern science, torque plays a fundamental role in simplifying complex problems efficiently. After understanding and reading their definition, and mathematical relationship with other physical quantities we can achieve great knowledge about this ubiquitous force that plays an essential role in the physical world.
As global transportation systems evolve, the debate over the most sustainable and cost-effective modes of rail travel intensifies. Electric and diesel railway systems represent two dominant technologies, each with distinct advantages and challenges.
In this article, we’ll look at the electric vs diesel locomotive debate by comparing the two in terms of their operational efficiency, financial implications, and environmental footprints.
With a deeper understanding of how they differ from one another, you can gain critical insights about their viability and the future of rail transport overall.
Let’s discuss in detail how each railway type compares according to these aspects:
When evaluating efficiency to generate answers amid the electric vs diesel locomotive debate, we need to look at three key factors: energy consumption, acceleration capabilities, and operational maintenance.
Energy Consumption
Electric railway systems are generally more energy-efficient than their diesel counterparts. Electric trains convert electrical energy into motion with a higher efficiency rate—often exceeding 90%. Additionally, electric trains can benefit from regenerative braking, which allows them to return energy to the grid when slowing down, further enhancing their efficiency.
In contrast, diesel engines typically operate at about 30-40% efficiency, primarily due to the energy losses associated with fuel combustion and mechanical conversion.
Acceleration
Electric trains are known for their superior acceleration capabilities. They can reach higher speeds more quickly than diesel trains, making them ideal for high-speed rail services and urban transit systems. This rapid acceleration is particularly advantageous in commuter rail scenarios, where frequent stops and starts are common.
Diesel trains, while capable of sustaining high speeds, often take longer to reach their peak performance due to the inherent limitations of their engines.
Operational Flexibility
While electric railway systems shine in terms of efficiency on electrified lines, diesel offers operational flexibility in regions where electrification is economically unfeasible. Diesel locomotives can operate on non-electrified tracks, making them a versatile choice for mixed-use rail networks. This flexibility allows for a more extensive reach in rural or less densely populated areas where infrastructure investments in electrification may not be justifiable.
Maintenance
Electric trains generally require less maintenance than diesel locomotives, primarily because they have fewer moving parts and do not rely on complex combustion systems. Besides, some parts of electric trains are out of reach of people who can easily destroy and vandalize. Overhead catenary system components like the cantilever and the contact wire, for instance, are suspended above the electric train railway tracks, unlike the key parts of a diesel train that are on the ground.
This reduced need for maintenance in electric trains can lead to lower downtime and higher overall availability, further enhancing their operational efficiency.
When comparing these two types of railway systems in terms of cost, we need to look at how they fare in terms of:
Initial Capital Investment
The upfront capital costs for electric railway systems can be substantially higher than those for diesel systems. Electrifying a railway line involves significant infrastructure investments, including the installation of overhead wires or trackside electrification equipment, substations, and signal systems. These costs can be prohibitive for engineering companies , especially in regions where rail networks are underdeveloped.
Conversely, diesel locomotives require lower initial investments, as they can operate on existing tracks without the need for electrification, making them more accessible for regions with budget constraints or limited rail infrastructure.
Operational Costs
Once operational, though, electric trains often demonstrate lower variable costs. The price of electricity is typically more stable and can be cheaper than diesel fuel, especially as renewable power sources become more prevalent. Additionally, electric trains benefit from lower maintenance costs due to fewer moving parts and the absence of complex engine systems.
On the other hand, diesel locomotives face higher fuel costs and more frequent maintenance requirements, which can lead to increased operational expenditures over time.
Subsidies and Incentives
Government policies and subsidies also influence the cost landscape. Many governments like the United States are increasingly promoting electrification as part of their sustainability goals, leading to grants and incentives that can alleviate some of the financial burdens associated with electric railway development. The Clean Electricity Investment Tax Credit, for instance, incentivizes renewable energy production, with additional bonuses to eco-projects that also leverage manufacturing materials that are sourced domestically or are in energy communities. These are communities that traditionally relied on fossil fuel-related jobs.
Diesel railway systems, while less capital-intensive initially, may face higher operating costs in the future due to potential regulations aimed at reducing emissions.
The environmental impact of electric and diesel railway systems is a critical consideration as societies strive for sustainable transportation solutions. Let’s look at the electric vs railway locomotive debate from this perspective by analyzing each type in terms of greenhouse gas emissions, energy sources, and noise pollution.
Greenhouse Gas Emissions
Electric railway systems have a distinct advantage in terms of greenhouse gas emissions. While the manufacturing and construction phases of electric systems can produce emissions, the operational phase is significantly cleaner. Electric trains can reduce carbon emissions by up to 70% compared to diesel, especially in regions with green energy integration.
In contrast, diesel trains emit considerable amounts of CO2 and other pollutants during operation, contributing to air quality degradation and climate change.
Energy Sources
The environmental benefits of electric railway systems heavily depend on the energy mix used for electricity generation. In areas where coal or fossil fuels dominate the energy landscape, the emissions associated with electric trains can still be substantial. However, as the global shift toward renewable energy accelerates, the environmental footprint of electric railways is expected to diminish further.
Diesel trains, relying solely on fossil fuels, on the other hand, face increasing scrutiny as the world moves toward decarbonization.
Noise Pollution
Electric trains are generally quieter than diesel locomotives, particularly at lower speeds. The absence of a combustion engine allows electric trains to operate with less operational noise, which is beneficial for urban environments and communities near rail lines.
Diesel trains, however, produce significant noise from both their engines and the mechanical vibrations associated with rail travel, which can impact quality of life for nearby residents.
Land Use and Habitat Disruption
Both systems can impact land use and ecosystems during construction and operation. However, railway electrification can often minimize additional land disruption. Diesel railway systems might require less initial infrastructure but can still contribute to habitat fragmentation through their operational footprint.
Diesel locomotives, while offering initial cost advantages and operational flexibility, generally have higher long-term costs and a more significant environmental footprint. Electric railway systems, meanwhile, are better in terms of efficiency and environmental impact than diesel.
But as the global community places even more premium on environmental protection, they’ll rely even more on clean energy as their source of power and find more ways to reduce their carbon footprint. That means that while the electric vs diesel locomotive debate still continues, electric vehicles including railway systems that rely on clean energy are expected to dominate the landscape in the future.
Smart cities aim to improve urban life by leveraging modern technology to create efficient, responsive, and sustainable environments. A critical element in enabling these advanced systems is connectivity.
Smart cities strongly rely on high-speed and reliable Internet infrastructure for the Internet of Things (IoT), industrial systems, and other digital services.
One of the most effective solutions for smart city connectivity is Metro Ethernet. Metro Ethernet presents an effective solution for smart city connectivity. No wonder the market size is projected to reach $113300.89 million by 2031 at a rapid annual growth rate of 10.7%.
With metro ethernet connections, smart cities have the robust, flexible, and scalable network that they need to thrive.
This article explores the role of metro ethernet in supporting smart cities, its benefits, and why it's the right choice for enhancing IoT and industrial systems.
Metro Ethernet is a network that connects users within a metropolitan area through ethernet technology, which is commonly used in local area networks (LANs). However, when applied at a larger scale, Metro Ethernet provides city-wide or even regional connectivity.
There are different types of Metro Ethernet services based on how they are structured:
E-line is a point-to-point connection that links two locations. It's like having a direct, private link between two sites, allowing for secure, high-speed data transfer.
E-Line can be used in smart cities to connect specific systems like traffic control centers, energy management hubs, or emergency response centers, ensuring real-time, secure communication between critical locations.
This is a point-to-multipoint network, where one location (like a central data center) connects to multiple sites (like smaller city branches).
As seen above, the E-tree model is often used in IoT systems where sensors and devices report back to a central hub.
E-LAN is a multipoint-to-multipoint network, allowing multiple sites to connect as if they are on the same LAN.
E-LAN is particularly useful for smart cities where various systems, like traffic control and energy management, need to communicate across different locations.
E-Access provides wholesale connectivity between different networks. It enables one service provider to extend its network reach by connecting to another provider's network through a standardized Ethernet interface. This service is useful in situations where a provider needs to offer Ethernet services in locations where they don't have direct infrastructure.
Each of these Metro Ethernet services can be adapted to suit the needs of different smart city applications, offering a range of options depending on the size and scale of the deployment.
Metro Ethernet operates similarly to the traditional Ethernet technology used in offices and homes, but it is scaled up to provide connectivity over large distances, often spanning entire cities.
Metro Ethernet creates a high-speed , wide-area network that connects multiple locations within a city or region. With this, businesses and organizations to connect their various offices or sites as if they were on the same local network, even if they're physically far apart.
Metro Ethernet supports various services like internet access, voice over IP (VoIP), file sharing, and private line connections. The technology uses switches and routers to direct traffic efficiently across the network, ensuring data reaches its intended destination quickly and securely.
Here’s a simple illustration of how a typical metro ethernet works:
Metro Ethernet is managed by a service provider that maintains the infrastructure and ensures the network's performance.
In smart cities, connectivity is critical. IoT devices like sensors, cameras, and meters generate massive amounts of data that need to be processed and acted upon in real-time. Industrial systems, on the other hand, require reliable, high-speed connections to ensure smooth operations.
Metro Ethernet excels in these areas, offering a range of benefits that make it ideal for smart city applications:
Smart cities rely on real-time data to manage everything from traffic lights to public safety systems. With high-speed Metro Ethernet, these systems can transmit data instantly, ensuring that decisions are made quickly and accurately.
Metro Ethernet offers speeds that can range from 10 Mbps to over 100 Gbps, depending on the needs of the city or business. This high-speed connectivity is essential for IoT devices and industrial systems that generate and consume vast amounts of data.
One of the key advantages of Metro Ethernet is its simplicity. It operates using the same Ethernet protocol that many IT teams are already familiar with, making it easier to manage compared to more complex network architectures.
For smart city administrators, this ease of use means less time spent on troubleshooting and more time focusing on optimizing services like energy distribution, waste management, and public transport systems.
Metro Ethernet is highly flexible, allowing cities to scale their network as needed. This is crucial for smart cities where the number of connected devices is constantly growing. Whether it’s expanding coverage to new areas of the city or addressing the increasing bandwidth demand from more and more devices, Metro Ethernet can easily accommodate these needs.
Also, a smart city network supports a wide variety of critical applications, from low-bandwidth devices like smart meters to high-bandwidth systems like video surveillance. Metro Ethernet can handle this diversity by offering customizable service packages that fit the specific needs of different systems.
While the initial investment in Metro Ethernet infrastructure may seem high, it is generally more cost-effective in the long run. Traditional networks often require expensive hardware upgrades and complex management systems. Metro Ethernet, on the other hand, uses a simpler, more unified approach that reduces both capital and operational expenses.
For smart cities, which need to connect numerous systems across large areas, Metro Ethernet offers an affordable way to maintain a high-performance network without ongoing high costs. Additionally, service providers often offer scalable pricing models, so cities only pay for the bandwidth and services they need.
Metro Ethernet is known for its high reliability. Recent market analysis reveals that 50% of subscribers expect at least 99.99% service availability— and this is what most service providers often offer in service level agreements (SLAs). This level of reliability is critical because city services often need to operate without interruption.
For instance, stable Metro Ethernet connectivity ensures that essential services like emergency response systems are always online or that energy distribution is consistent.
As smart cities grow, so do their connectivity needs. Metro Ethernet can scale easily to accommodate more users, devices, and systems. Whether the city is expanding its smart traffic management systems or adding new IoT devices, there’s room for quick adjustments in bandwidth and service levels.
Also, scalability is particularly important in industrial systems, where data demands can fluctuate depending on the time of day or operational requirements. Metro Ethernet's ability to scale up or down as needed ensures that the network remains efficient and cost-effective.
Metro Ethernet is an essential tool for smart cities looking to enhance their connectivity. Its high-speed, reliable, and scalable nature makes it the perfect choice for supporting the growing number of IoT devices and industrial systems that modern cities rely on.
As smart cities continue to evolve, having a solid network foundation like Metro Ethernet is crucial. It not only ensures that current systems operate efficiently but also provides the flexibility needed to support future innovations.
