Question

What is the moment of inertia of a pendulum with a mass of `5 kg` that is `8 m` from the pivot?

Answer 1

`320kg.m^2`

Explanation:

Assuming simple pendulum, where the mass and dimensions are relatively small compared to the mass of the bob, we may use the approximation :

`I=MR^2`

`=5xx8^2`

`=320kg.m^2`.
