A simple pivot-type gripper, shown in Fig. P. 7.9.2(a), is used to lift a rectangular block of 3 kg mass. It is to be lifted vertically at a velocity of 2 m/s and with a acceleration of 15 m/s. The coefficient of friction between gripping pads and block is 0.45. If the required factor of safety is 1.5, determine : the gripping force, and 1. 2. the actuating force.
