Question

What do you mean by moment of inertia and radius of gyreation of a body?​

Answer 1

Answer:

Radius of gyration or gyradius of a body about the axis of rotation is defined as the radial distance to a point which would have a moment of inertia the same as the body's actual distribution of mass, if the total mass of the body were concentrated there. ... One can represent a trajectory of a moving point as a body.
