Graduate Derivation of Moment of Inertia: Why is centripetal acceleration ignored?
Ok, I understand the solution to the first problem because I forgot to use the correct definition of a moment which is, τ = r x F. For the second problem I have something to clarify. A torque, τ is exerted on a solid object on a horizontal and rough surface. The torque, τ is a couple. That is... -

Graduate Derivation of Moment of Inertia: Why is centripetal acceleration ignored?
Moment of inertia, I is the resistance of an object to rotational motion. It is the rotational analogue of mass and is given by the following integral, I = \intmiri2 . A simple derivation was explained to me as follows. A moment, τ is the product of force, F and lever arm, r. τ = F*r...
