2 Masses on a Pulley - Torque Demonstration

By Flipping Physics, 02/10/2019

Example: 0.100 kg and 0.200 kg masses hang from either side of a frictionless #Pulley with a rotational inertia of 0.0137 kg·m^2 and radius of 0.0385 m. (a) What is the #AngularAcceleration of the pulley? (b) What is the #TensionForce in each string? Want Lecture Notes? This is an AP Physics 1 Topic.
