n the following drawing, the system is a swivel chair, a person is on the chair and the bicycle wheel being held at armlength. The moment of inertia of the person and swivel chair is I0. The moment of inertia of the bicycle wheel around its center axis is I1. (a) The wheel is horizontal at a distance L from the chair axis. Give the total moment of inertia of the system around the swivel axis. (b) The wheel is rotated at w1, vector pointing up, and the chair is not rotating. Give the total angular momentum of the system. (c) The person flips the wheel upside down. Give the bicycle wheel’s new rotation speed and direction, and give the system’s rotation speed, w0 , and direction.

(c) The person flips the wheel upside down. Give the bicycle wheel’s new rotation speed and direction, and give the system’s rotation speed, w0 , and direction. Assume that the chair swivel has no friction and identify the components of the total torque that are always zero.
