A thin circular ring is rotating about an axis passing through its center and perpendicular to its plane. Find the moment of inertia of the ring about its diameter.

A thin circular ring is rotating about an axis perpendicular to its plane. State the theorem which will help you to find the moment of inertia about its diameter.

What is the radius of gyration of the ring about an axis passing through its centre mass and perpendicular to its plane?

Moment of inertia plays the same roll in rotational motion as mass in linear motion. The moment of inertia of a body changes when the axis of rotation changes.If the moment of inertia of a disc about an axis passing through its centre and perpendicular to its plane is (MR^2)/2) ( M is the mass of the disc and R its radius). Determine its moment of inertia about a diameter and about a tangent.
