massless rope passes over a? The drawing shows box 1 resting on a table, with box 2 resting on top of box 1. A massless rope passes over a massless, frictionless pulley. One end of the rope is connected to box 2 and the other end is connected to box 3. The weights of the three boxes are W1 = 50.8 N, W2 = 33.6 N, and W3 = 26.1 N. Determine the magnitude of the normal force that the table exerts on box 1.
