Rotational Dynamics Problem 8.6.5

Description

Two masses, M = 2.5 kg and m = 1.0 kg, are attached with a massless string over a pulley as shown in the animation (position is in centimeters and time is in seconds). The bearings in the pulley are frictionless and the string does not slip.

Question

What is the moment of inertia of the pulley? Start

Answer

I = 0.27 kg m2.
