Question

A If the sum of the torques on an object in equilibrium is zero about a certain point, it is

Answer 1

Answer:

If a the sum of the torques on an object in equilibrium is zero about certain point , it is called rotational equilibrium .

Explanation:

A body is considered to be in rotational equilibrium if the vector sum of all torques operating on it is zero.

If an object's rotational velocity is constant, it is said to be in rotational equilibrium. An item in rotational equilibrium would be one that is not rotating or rotating at a consistent pace in one direction.

Hence ,  the net torque applied on the object must be zero for it to be in rotational equilibrium.

Answer 2

Rotational equilibrium occurs when the sum of the torques on an object in equilibrium is zero around a specific location.

• If the vector sum of all torques acting on a body is zero, it is said to be in rotational equilibrium.
• A rotating object is considered to be in rotational equilibrium if its rotational velocity remains constant.
• An object in rotational equilibrium is not rotating or rotating at a constant speed in one direction.

Is an object in equilibrium if the net torque is zero?

• If the size and direction of the torques acting on an object are exactly balanced, then there is no net torque acting on the object and the object is said to be in equilibrium.

When the net force on an object is zero the object motion will?

• An object with no net forces acting on it which is initially at rest will remain at rest.
• If it is moving, it will continue to move in a straight line with constant velocity.

What does it mean if torque is zero?

• If Torque = 0 ; that means either Force (perpendicular) = 0 , or Radius = 0; Case I : If Force (perpendicular) = 0; that means Acceleration (perpendicular) will be equal to 0; therefore Velocity (perpendicular) won't change .
• This implies Angular Momentum (L=mvr) won't change.
• Angular Momentum remains constant.

Hence ,  the net torque applied on the object must be zero for it to be in rotational equilibrium.
