Question:
Figure shows the pendulum of a clock. The uniform rod of length L = 2.0 m has a mass m = 0.8 kg. Attached to the rod is a disk of mass M = 1.2 kg and radius 0.15 m. The clock is constructed to keep perfect time if the period of the pendulum is exactly 3.50 s.
(a) What should be the distance d so that the period of this pendulum is 3.50 s?
(b) Suppose that the pendulum clock loses 5.0 min per day. How far and in what direction should the disk be moved to ensure that the clock will keep perfect time?
