Question

State perpendicular axis theorem. what is the moment of inertia of a ring of mass 2 kg and radius 0.5 m about an axis passing through its centre and perpendicular to its plane? also find moment of inertia about a parallel axis through its edge

Answer 1

In physics, the perpendicular axis theorem (or plane figure theorem) can be used to determine the moment of inertia of a rigid object that lies entirely within a plane, about an axis perpendicular to the plane, given the moments of inertia of the object about two perpendicular axes lying within the plane.
