Question

The moment of inertia of the wheel is 8kg.m2. Its radius is 40cm. Find the angular velocity of the wheel caused by the 10kg mass if the friction force bwtween the mass and the incline is 30N?

Answer 1

Answer:Since Moment of Inertia is addition of mass times distance squared for all the small masses comprising the body, the presence of all the mass at the max possible distance makes it have a large value of moment of inertia as compared to disk or solid sphere where almost every small mass is at lower distance.
