Question
Question 5 A pendulum consists of a rod AB of length 2L and mass m with a thin disc of mass M and radius r attached rigidly at its centre to the rod’s end point B. The pendulum rotates about an axis through point A of the rod, perpendicular to the plane of the disc. If the zero energy level of the (gravitational) potential energy is taken to go through point A, find the potential energy of the pendulum in the following cases: 1. If the pendulum is horizontal; (4) 2. If the pendulum stands upside down vertically above point A; (4) 3. If the pendulum forms the angle 45◦ with a vertical line drawn directly downwards from A.
