frictionless pulleys as shown. If the angle 0 = 43°, determine
the force that must be applied to the rope, Frope, to lift a
load of 3.8 kN. The three-pulley and hook assembly at the
center of the system has a mass of 21.5 kg with a center of
mass that lies on the line of action of the force applied to the
hook.
