Question

What is the moment of inertia of a rod with a mass of `7 kg` and length of `18 m` that is spinning around its center?

Answer 1

The answer is `=189 kgm^2`

Explanation:

The moment of inertia of a rod is `I=1/12ml^2`

`m`=mass of the rod=7kg

`l=`length of the rod=18m

`I=1/12*7*18^2=189 kgm^2`
