WHP02-Q2 The hydraulic cylinder produces a limited horizontal motion of point A. When 0 = 45, VA = 2 m/s and a = 0.5 m/s in the directions shown in the figure, determine: (a) the angular velocities (magnitudes and directions) of links ABD and OB, (b) the velocity (magnitude and direction) of point D, (c) the angular acceleration (magnitude and direction) of link OB. A aA VA 400 200 mm mm OD 250 mm Answers: (a) ABD = 3.734 rad/s CCW, @B = 7.578 rad/s CW; (b) VD 2.249 m/s (c) OB = 44.969 rad/s CCW
