Question

What is the moment of inertia of a pendulum with a mass of `7 kg` that is `10 m` from the pivot?

Answer 1

`700kg.m^2`

Explanation:

Assuming it is a simple pendulum, (dimensions small and mass of string negligible), we may find the moment of inertia of the pendulum bob about the axis of rotation as follows :

`I=MR^2`

`=7xx10^2`

`=700kg.m^2`
