In order to prevent muscle contraction from misaligning bones during healing (which can cause a permanent limp), injured or broken legs must be supported horizontally and at the same time kept under tension (traction) directed along the leg. One version of a device to accomplish this aim, the Russell traction apparatus, is shown in (Figure 1). This system allows the apparatus to support the full weight of the injured leg and at the same time provide traction along the leg.

If the leg to be supported weighs 43.0 N, what must be the weight of W? Express your answer in newtons
