A solid disk of mass M is mounted at pivot point A such A that it can swing back and forth in simple harmonic motion. The disk has a radius r. It is being pulled to an angle 6'0 and released from rest (see gure). Your ultima_te__gol is to find the mathematical equation 4" describing the pendulum's motion. M = 5.00 kg r = 1.5II]I m I90 = 1C!\" a. Draw the extended FED of the disk for an arbitrary . angle 6' during the motion. ' A b. What forceis] produce a nonzero torque about the pivot point A? c. For the instant shown in the FBD, assuming the angle 6' = 5\d. Using the parallelaxis theorem, nd the moment of inertia of the disk about point A. e. Find the angular acceleration of the disk at the position shown [B = 5"). f. Find the period T for the SHM of the disk. Hint: revisit the notes on the physical pendulum. You do not have to do a full derivation
