Problem 6. The circular plate shown rotates about its vertical diameter. At the instant shown, the angular velocity ₁ of the plate is 10 rad/s and is decreasing at the rate of 25 rad/s². The disk lies in the XY plane and Point D of strap CD moves upward. The relative speed u of Point D of strap CD is 1.5 m/s and is decreasing at the rate of 3 m/s². Determine (a) the velocity of D, (b) the acceleration of D. Answers: =0.75 +1.299]-1.732k m/s a=-28.6 +3.03-10.67k m/s² 200 mm x Z

Problem 1. The flywheel A has an angular velocity o 5 rad/s. Link AB is connected via ball and socket joints to the flywheel at A and a slider at B. Find the angular velocity of link AB and the velocity of slider B at this instant. (Partial Answer: @ABN = -2î + 2.25; red Z -1.2 ft C -7 Y -1.5 ft- B 2.0 ft
