Question

What is the moment of inertia of a pendulum with a mass of `7 kg` that is `4 m` from the pivot?

Answer 1

`moment=280 Nm`

Explanation:

first of all convert `7kg` into Newtons by multiplying by `10` as it is the gravitational force.
so `7*10=70N`
now apply the formula
`moment= N *d`
`moment=70*4`
`moment=280 Nm`
