Problem 4.5 Consider the split Russel traction device and a me-chanical model of the leg shown in Figure 4.53. The leg is held in the position shown by two weights

that are connected to the leg via two cables. The combined weight of the leg and the cast is W = 300 N. l is the horizontal distance between points A and B where the cables are attached to the leg. C is the center of grav-ty of the leg including the cast, which is located at a distance two-thirds of e as measured from A. The angle cable 2 makes with the horizontal is measured as ß = 45°. Determine the tensions T₁ and T₂ in the cables, weights W₁ andW₂, and angle a that cable 1 makes with the horizontal, so that the leg remains in equilibrium at the position shown.
