A pendulum is made of a rod of mass 1.7kg and length 3.8m whose moment of inertia about its center of mass is (1/12) ML^2 and a thin cylindrical disk of mass 2.4kg and radius 1.8m whose moment of inertia about its center of mass is .5mr^2. What is the moment of intertia of the pendulum about the pivot point? Answer in units of kg * m^2
