The pendulum consists of a uniform disk with radius 9.3 cm and mass 456 g attached to a uniform rod with length 46 cm and mass 222 g. The rod is attached to the edge of the disk and rotates around a pivot at its other end.
(a) Calculate the rotational inertia of the pendulum about the pivot point.
(b) What is the distance between the pivot point and the center of mass of the pendulum?
(c) Calculate the period of oscillation.
