A wheel is attached to a fixed shaft, and the system is free to rotate without friction. To measure the moment of inertia of the wheel– shaft system, a tape of negligible mass wrapped around the shaft is pulled with a known constant force F. When a length L of tape has unwound, the system is rotating with angular speed ω0. Find the moment of inertia I0 of the system.

1. Two 20kg pods are attached to the ends of a 4m massless bar. A motor applies an increasing moment approximated by M = 6001 (Nm) to a connecting shaft which causes the pods to rotate. Determine how fast the pods are traveling after 4 seconds if the friction in the motor's bearings is approximately 80Nm, respectively. Ignore wind resistance and the mass of the rotating shaft.
