Question

What is the radius of gyration? On what factors it's depends?

Answer 1

The radius of gyration:

1. The radius of gyration is commonly defined as the distance from the axis of rotation to a point where the total mass of anybody is assumed to be concentrated so that the moment of inertia about the axis remains constant.
2. It is the perpendicular distance between the point mass and the axis of rotation.

The radius of gyration is affected by the following factors:

1. Shape and size of the body
2. Position and configuration of an axis of rotation
3. Distribution of mass of the body about the axis of rotation
