Define moment of inertia of a rigid body. Find the moment of inertia of a circular ring about an axis passing through its center and perpendicular to its plane.

Answer»

Themoment of inertia, otherwise known as the angular mass or rotationalinertia, of a rigid bodyis a tensor that determines the torque needed for a desired angular acceleration about a rotational axis; similar to how mass determines the force needed for a desired acceleration.
