When the thumbscrew in the vise grips shown in Figure is rotated, the effective pivot point of the 7.0-cm link is moved. During this motion, the spring prevents the jaws from moving. Graphically position the links as the effective pivot point is moved 2 cm to the right. Then reposition the links as the top jaw is opened 40° from the new orientation, while the lower jaw remains stationary. Determine the resulting angular displacement of the top handle.
