Question

define radiuns of gyration of a body and write the expression for it​

Answer 1

Answer:

The radius of gyration of a body rotating about an axis is defined as the distance between axis of rotation and the point at which entire mass of the body can be supposed to be concentrated so as to give the same moment of inertia as that of body about given axis. I=MK^2.
