Answer 2

Answer:

Radius of gyration is defined as the distance between the center of gravity and the axis about which body is rotating . Generally radius of gyration is denoted by K.

It is given by the formula,

K = √I/m

where,

I = moment of inertia

m = Mass of the body

Radius of Gyration depends upon the following factors:

1) Moment of inertia of the body

2) Mass of the body

3) Shape and size of the body

4) position of the axis of rotation
