Traction is another medical application of balanced forces acting at the center of mass. Traction technology uses weights, ropes, and pulleys to apply force to tissues that surround broken bone. In the figure below, the lower leg is lifted and extended away from the femur in order to reduce pain and encourage proper alignmnent while healing. Femur X Enter to 3 significant figures 30° 30° If the weight attached at the lower end of the rope is 70.0 N, and the system is in static equilibrium, then what is the extension force (x-component only) acting on the femur?
