In order for a rigid body suspended by a pivot to be in rotational equilibrium, its point of suspension must be vertically above its centre of gravity.

Question

Quizplus · Accepted Answer

The point of suspension must be vertically above the center of gravity for a rigid body suspended by a pivot to be in rotational equilibrium. This is because the torque due to the weight of the body must be balanced by the torque due to the tension in the pivot. If the point of suspension is not vertically above the center of gravity, the torque due to the weight of the body will cause the body to rotate.
