Question

If the radius of gyration of a body of mass 0.25kg is 100kg-m² . What is the moment of inertial of body

Answer 1

Given :-

Mass of body = m = 0.25 kg

Radius of gyrating = R = 100 Kgm²

Equation of Radius of Gyration = MK²

As we know that,

Moment of Inertia = Radius of Gyration

I = MK²

I = 100 Kgm²

Actually, Radius of Gyration is used to compare or check how a body will behave under compression along axis.

It is used to check bending in a compression member or beam, however, it has same value because radius is constant.

It is also the root mean of square distance of various particles or body from the axis of rotation.
