Question

In the three-bar linkage shown in the figure, the control link CD has a constant clockwise angular velocity of 120 rev/min (remember to convert to rad/s). Determine (a) the velocity of point C by the Vector Method; (b) the angular velocity of link BC and the velocity of point B by the Instantaneous Center of Zero Velocity method; (c) the angular velocity of link AB by the Scalar Method; (d) the acceleration of point C by the Scalar Method; and (e) the angular velocity of links BC and AB by the Vector Method. Express all answer in polar form.
