The 5-lb rod AB supports the 3-lb disk at its end A. If the disk is given an angular velocity while the rod is held stationary and then released, determine the angular velocity of the rod after the disk has stopped spinning relative to the rod due to frictional resistance at the bearing A. Motion is in the horizontal plane. Neglect friction at the fixed bearing B.
