In order to prevent muscle contraction from mis-aligning bones during healing, broken legs must be supported horizontally and kept under tension (traction) directed along the leg. If the leg weighs [w] N, what must be the weight of the hanging mass ? The supporting wires make an angle of 30 degrees with respect to the floor.

In order to prevent muscle contraction from mis-aligning bones during healing, broken legs must be supported horizontally and kept under tension (traction) directed along the leg. If the leg weighs [w] N, what traction force does this hanging weight produce upon the leg ? The supporting wires make an angle of 30 degrees with respect to the floor. Hint 1: Tension in the wires is equal to the hanging weight. Hint 2 : Which component of the weight/tension contributes to the traction of the leg ? Hint 3: Forcealong the leg=2⋅Weight⋅cosθ
