A four-bar linkage is shown in the figure (the ground "link" OC is considered the fourth bar). If the angular velocity and angular acceleration of drive link OA are 6.1 rad/s and 6.6 rad/s² respectively, both counterclockwise, determine the angular accelerations of bars AB and BC for the instant represented. The angular accelerations are positive if counterclockwise, negative if clockwise. The answers are not 2.356 and 11.327, or 390.82 and 465.7

The disk shown in the figure rotates, at the instant shown, with a clockwise angular velocity of 40 rad/s and with a counter clockwise angular acceleration of 5 rad/s2. How long does it take before the disk comes to a temporary stop? a = 5 rad/s
