The hydraulic cylinder pushes link BC causing the rotation of link OA about fixed O. At this instant, link BC is moving at 5 m/s while its speed is increasing at the rate of 25 m/s². Also, at this instant, link AB is horizontal while link OA is vertically oriented. Determine (a) the total acceleration at A, and (b) the angular acceleration of link OA. Let angle = 40°. Note: Use purely RMA Method in your calculations. B C B VB 250 mm " A 125 mm 0
