The hydraulic cylinder produces a limited 200 horizontal motion of point A. When 0 = 45, mm vA = 2 m/s and aA= 0.5 m/s in the D directions shown in the figure, determine: 400 mm (a) the angular velocities (magnitudes m and directions) of links ABD and OB, A (b) the velocity (magnitude and direction) of point D, aA VA (c) the angular acceleration (magnitude and direction) of link OB. Answers: (a) (ABD = 3.734 rad/s CCW, wos = 7.578 rad/s CW; (b) VD= 2.249 m/s (c) COB = 44.969 rad/s2 CCW
