Chris’ rad bicycle wheel has a radius of 38 cm and is given an angular acceleration of 2.67 rad/s2 by applying a force of 0.35 N on the edge of the wheel. What is the wheel’s moment of inertia? A toy top has a rod with a diameter of 8.0 mm and a disk of mass 0.0125 kg and diameter of 3.5 cm. The moment of inertia of the rod can be neglected.

Angular momentum is any quantity that obeys the commutation relations (1) and (2). The same relations apply to all types of angular momentum. These relations constitute one of the great generalizations of physics and provide the basis for the structure of the periodic table and the organization of …
