Question

What is the moment of inertia of a pendulum with a mass of `7 kg` that is `5 m` from the pivot?

Answer 1

moment of inertia = `175 kg * m^2`

Explanation:

As the mass of the connecting rod is not given it means that it is weightless we can ignore it.

`color (red)(I = mr^2)`

Where I is moment of inertia
m is mass
r is the distance from pivot

`I = 7*5^2`

`175 kg * m^2`
