*20-8. The disk rotates about the shaft S, while the shaft is turning about the z axis at a rate of w̟ = 4 rad/s, which is increasing at 2 rad/s². Determine the velocity and acceleration of point A on the disk at the instant shown. No slipping occurs. D2 rad/s 4 rad/s B- 0.1 m 0.5 m 0.1 m

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.
