An object is in rotational equilibrium **if the velocity of its rotation is constant**. An object that is not rotating or an object that is rotating in one direction a constant rate would be considered in rotational equilibrium. To be in rotational equilibrium, the net torque acting on the object must be zero.

## What are the condition for translation and rotational equilibrium?

**If an object at rest or if it has uniform linear velocity under the action of many forces it** is said to be in translational equilibrium. I f an object is at rest or if it has unifrom angular velocity under the action many torques , it is said to be rotational equilibrium.

## What condition or conditions are necessary for rotational equilibrium?

For an object to be in equilibrium, it must be **experiencing no acceleration**. This means that both the net force and the net torque on the object must be zero.

## What are the condition of equilibrium?

The two conditions that are important for equilibrium:- **The sum or resultant of all external forces acting on the body must be equal to zero**. The sum or resultant of all external torques from external forces acting on the object must be zero.

## What conditions must be met in order for an object to be in rotational equilibrium?

what is required for an object to be in rotational equilibrium. For an object to be in rotational equilibrium **the sum of the torques acting on it must be zero**.

## 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 is 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 the 1st and 2nd 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)**. These two conditions must be simultaneously satisfied in equilibrium.

## What is the first condition of equilibrium?

The first condition of equilibrium is that **the net force in all directions must be zero**.

## Which condition is required by a body to be in translational equilibrium?

An object is said to be in Translational Equilibrium Translational Equilibrium if and **only if there is no resultant force**. This means that the sum of all acting forces is zero. Force diagrams are necessary for studying objects in equilibrium.

## Can a moving body be in equilibrium?

Yes, **a body can be in equilibrium if it is in motion**. We call this type of equilibrium as a dynamic equilibrium. We know that a body is said to be in equilibrium if the net force acting on it is zero. By the second law of motion, we know that the acceleration in such bodies is zero.

## 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.

## 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.

## How do you know if a rod is in equilibrium?

For an object to remain in equilibrium, two conditions must be satisfied – **both the net force and the net torque must be equal to zero**. An example of an object in equilibrium is a rod that is free to rotate about a hinge at one end.

## How do you know if an object is in equilibrium?

If an object is at equilibrium, then **the forces are balanced**. Balanced is the key word that is used to describe equilibrium situations. Thus, the net force is zero and the acceleration is 0 m/s/s. Objects at equilibrium must have an acceleration of 0 m/s/s.

## 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.
