Question

A wheel is rotating at a rate of 1000 r.p.m and its
kinetic energy is 10° J. Determine the moment of
inertia of the wheel about its axis of rotation.​

Answer 1

Answer:

Explanation:

The Angular velocity of the body is given by

?=2wx1000/60 per second

= 100w/3 per second

KE = Iw2/2 = 106

So I =2x106/w2

I = 3x3x2x106/104w2 = 1800/w2 = 181.96 Js2
