Question

BK-92 (10B) A uniform disc has mass m and radius r. The disc is pivoted in the vertical plane at the midpoint of a horizontal radius, marked by a red line as shown. Initially, the disc is held at rest. After it is released, the disc swings downward, rotating about the pivot point. The acceleration due to gravity is g. axis of rotation Neglecting all resistive forces, find the following quantities at the moment immediately after the disc begins to move: Part 1. The rotational inertia of the disc relative to the axis of rotation. Part 2. The net torque acting on the disc. Part 3. The angular acceleration of the disc. Part 4. The linear acceleration of the center of the disc. Part 5. The magnitude of the normal force acting on the disc.
