Figure 4.27a shows a traction device used with a foot
Chapter 4, Problem 4.60(choose chapter or problem)
Figure 4.27a shows a traction device used with a foot injury. The weight of the 2.2-kg object creates a tension in the rope that passes around the pulleys. Therefore, tension forces and are applied to the pulley on the foot. (It may seem surprising that the rope applies a force to either side of the foot pulley. A similar effect occurs when you place a finger inside a rubber band and push downward. You can feel each side of the rubber band pulling upward on the finger.) The foot pulley is kept in equilibrium because the foot also applies a force to it. This force arises in reaction (Newtons third law) to the pulling effect of the forces and . Ignoring the weight of the foot, find the magnitude of .
