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.

Engineering DYnamics The bar AB shown rotates at 12 rad/s clockwise. Determine the angular velocities of bars BC and DC.

The wheel shown rolls on the hub without slipping along the fixed horizontal plane. The velocity of C is 1.9 m/s to the right. Determine the velocity of A.
