Rod AB is attached to collars at its ends by ball- and-socket joints. If the collar A has a velocity of VA = 3 ft/s. determine the angular velocity of the rod and the velocity of collar B at the instant shown. Assume the angular velocity of the rod is directed perpendicular to the rod.

The rod is attached with ball-and-socket joints to smooth collars AA and BB at its end points. AA is moving upward at a constant speed of vAvAv_A = 6.6 ft/sft/s . The angular velocity of the rod is directed perpendicular to the axis of the rod.  Determine the magnitude of the velocity of BB at the instant shown Determine the xx, yy, and zz components of the angular velocity of the rod using scalar notation.

C16-3. The bi-fold hangar door is opened by cables that move upward at a constant speed of 0.5 m/s. Determine the angular velocity of BC and the angular velocity of AB when e = 45°. Panel BC is pinned at C and has a height which is the same as the height of BA. Use appropriate numerical values to explain your result.
