Assume that the physical pendulum in a grandfather's clock is composed of a uniform rod (mass mrod = 5M, length Lrod = 10R) pivoted at the top, with its lower end connected to a uniform disk (mass mdisk = M, radius rdisk = R). The expressions for the moments of inertia about the centers of mass are: Irod = (1/12) mrod Lrod2 and Idisk = (1/2) mdisk rdisk2.
