Answer #1

If the disk is not fixed to the rod, then it will not rotate about its center of mass as the
pendulum oscillates. Therefore the moment of inertia of the disk about its center of mass
does not contribute to the moment of inertia of the physical pendulum about the pivot
point. Notice that the pendulum is no longer a rigid body. The total moment of inertia is
only due to the rod and the disk treated as a point like object,12 ㄩˋ M7
