Pulleys of Unequal Mass

Concept Overview:

Relationship of moment of inertia to acceleration under the influence of constant torque

Lecturer Procedure

Step(s) to Follow

1. Tighten the masses around each pulley.
2. Release masses at the same time

Expected Result

The aluminum pulley rotates faster, since it has less mass, and therefore a lower moment of intertia. 

Under the same torque, it will experience a greater acceleration
