A pendulum consisting of a mass m and a string of length L = 22 cm is hung from the edge of a bicycle wheel of radius r = 26 cm whose axis of rotation has been fixed vertically. The wheel is spun around its axis faster and faster until the pendulum is seen to make an angle of approximately q = 45o from the vertical, as shown in the diagram below. At this point, what is the period of rotation for the wheel assembly?
