PROBLEM 6.90
(a) Show that when a frame supports a pulley at A, an equivalent loading of the frame and of each of its
component parts can be obtained by removing the pulley and applying at A two forces equal and parallel
to the forces that the cable exerted on the pulley. (b) Show that if one end of the cable is attached to the
frame at a Point B, a force of magnitude equal to the tension in the cable should also be applied at B.
