Question

5. Discuss the necessity of radius of

gyration. Define it. On what factors does

it depend and it does not depend? Can

you locate some similarity between the

centre of mass and radius of gyration?

What can you infer if a uniform ring and

a uniform disc have the same radius of

gyration?​

Answer 1

Radius of gyration

Explanation:

Radius of gyration is defined as the distance between the center of gravity and the axis about which body rotates. The radius of gyration depends on various factors like the size and shape of the body, configuration of its axis of rotation, the body's position and distribution of the mass with regard to its axis of rotation. The radius of gyration is the root mean square distance of the object from its center of gravity.

Answer 2

Answer:

radius of gyration is centre of mass
