If the rope is horizontal from box 2 to the pulley then the table is just carrying the weight of boxes 1 and 2
F = 52.4+38.4
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 = 52.4 N, W2 = 38.4 N, and W3 = 28.2 N. Determine the magnitude of the normal force that the table exerts on box 1.
