Question

what is the moment of inertia of a wheel of the bicycle ifit has a radius 65cm and 2.8 kg rotating about its center?

Answer 1

Given: Radius = 65cm = 0.65 m

           mass = 2.8 kg

To find: Moment of Inertia =?

Solution:

We know that,

I = mr²

So,  Moment of Inertia (I) = 2.8×0.65 = 1.82 kg.m²

So, the required answer is 1.82 kg.m² .( Ans)
