A grandfather clock uses a physical pendulum to keep time. The pendulum consists of a uniform thin rod of mass M = 2.01 kg and length L = 0.19 m that is pivoted freely about one end, with a solid disk of mass 3M and a radius of L/4 attached to the free end of the rod.
a) What the moment of inertia of the pendulum about its pivot point?
0.3711 kg*m*m
You are correct.

b) What is the period of the pendulum for small oscillations?
0.959 s
c) Determine the length L that gives a period of T = 2.49 s.
1.280 m
