What Is The 2nd Condition Of Equilibrium?

by | Last updated on January 24, 2024

, , , ,

The second condition necessary to achieve equilibrium involves

avoiding accelerated rotation (maintaining a constant angular velocity)

. A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it.

What is first and second condition of equilibrium?

Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and

the sum of all external torques from external forces is zero

(second condition of equilibrium). … If one of them is not satisfied, the body is not in equilibrium.

What is the formula of second condition of equilibrium?

According to the First condition of equilibrium sum of forces acting on a body is zero ( ∑ F =0 ), While according to the second condition of equilibrium sum of torque acting on a body is zero

( ∑ τ = 0 )

.

What are the three conditions of equilibrium?

  • The lines of action are coplanar (in the same plane)
  • The lines of action are convergent (they cross at the same point)
  • The vector sum of these forces is equal to the zero vector.

What are the main condition of equilibrium?

The equilibrium condition of an object exists

when Newton’s first law is valid

. An object is in equilibrium in a reference coordinate system when all external forces (including moments) acting on it are balanced. This means that the net result of all the external forces and moments acting on this object is zero.

Why do we need a second condition for equilibrium?

The second condition necessary to achieve equilibrium involves avoiding accelerated rotation (maintaining a

constant angular velocity

. A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it.

What is equilibrium simple words?


a state of rest or balance due to the equal action of opposing forces

. equal balance between any powers, influences, etc.; equality of effect. mental or emotional balance; equanimity: The pressures of the situation caused her to lose her equilibrium. Chemistry.

What does it mean if the body is equilibrium?

A simple mechanical body is said to be in equilibrium if

it experiences neither linear acceleration nor angular acceleration

; unless it is disturbed by an outside force, it will continue in that condition indefinitely.

Can a moving object be in equilibrium?

A moving object is in equilibrium if it moves with a constant velocity; then

its acceleration is zero

. A zero acceleration is the fundamental characteristic of an object in equilibrium.

What happens when forces are not in equilibrium?

Because there is no net force acting on an object in equilibrium, then from Newton’s first law of motion,

an object at rest will stay at rest, and an object in motion will stay in motion

. … Since the ball is initially at rest (velocity equals zero), the ball will remain at rest according to Newton’s first law of motion.

How do you find equilibrium conditions?

  1. Use the supply function for quantity. You use the supply formula, Qs = x + yP, to find the supply line algebraically or on a graph. …
  2. Use the demand function for quantity. …
  3. Set the two quantities equal in terms of price. …
  4. Solve for the equilibrium price.

How do you solve static equilibrium problems?

  1. Identify the object to be analyzed. …
  2. Set up a free-body diagram for the object. …
  3. Set up the equations of equilibrium for the object. …
  4. Simplify and solve the system of equations for equilibrium to obtain unknown quantities.

What happens to equilibrium constant when reaction is reversed?

The equilibrium expression written for a reaction written in the reverse direction is

the reciprocal of the one for the forward reaction

. K’ is the constant for the reverse reaction and K is that of the forward reaction. … The equilibrium expression is the reciprocal of that given.

Which condition is not true for the equilibrium in free body diagram?

2. Which one is not the condition for the equilibrium in free body diagram for calculation of the normal forces, consider all forces to be straight and linear? Explanation: For the equilibrium in the three dimensional system of axis we have all the conditions true as,

∑Fx=0

, ∑Fy=0 and ∑Fz=0.

What are the conditions for system to be in mechanical equilibrium?

A mechanical equilibrium exists when

all the mechanical forces within a system are balanced so that there is no acceleration

. A thermal equilibrium exists within a system when the temperature is uniform throughout so that there is no heat transfer within the system.

Is Balanced force considered to be in a state of equilibrium?

Balanced forces are considered to be in a state of equilibrium. When forces are balanced there is

no

change in direction. Balance forces cannot change the motion or direction of an object.
