The 2.deltadeltadeltadelta kg slender rod AB is pinned at C and supports the rotating disks A and B in a horizontal plane.  The 1kg disks are given an initial angular velocity of w_B=5rad/s and w_A=3.3rad/s while the rod AB is held in place.   The rod is then released but friction at bearings A and B soon brings the rotating disks to rest relative to rod AB.  Determine the angular velocity of rod AB when the disks comes to rest, assuming friction at bearing C is negligible.
