Bar OC rotates with a clockwise angular velocity woc = 5.3 rad/s and a counterclockwise angular acceleration doc = 4.6 rad/s². The bar OC is a slotted member which accommodates the pin A attached to the sector. Determine the angular velocity w and the angular acceleration a of the sector. The angular velocity and the angular acceleration are positive if counterclockwise, negative if clockwise. Assume OA = 500 mm, d = 385 mm, 0 = 21°. Answers: W = B a = i i d aoc rad/s rad/s² @oc
