The 12-kg rod ab is pinned to the 40-kg disk. if the disk is given an angular velocity ω d = 100 r a d / s while the rod is held stationary, and the assembly is 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 b. motion is in the horizontal plane. neglect friction at the pin a.
