Leg traction. The accompanying figure shows how a leg may be stretched by a pulley line
Chapter 5, Problem 13(choose chapter or problem)
Leg traction. The accompanying figure shows how a leg may be stretched by a pulley line for therapeutic purposes. We denote by F\ the vertical force of the weight. The string of the pulley line has the same tension everywhere; hence, the forces Fj and F3 have the same magnitude as F\. Assume that the magnitude of each force is 10 pounds. Find the angle 0 so that the magnitude of the force exerted on the leg is 16 pounds. Round your answer to the nearest degree. (Adapted from E.
