Knee Extension. Consider a person wearing a cast on their foot of weight W,-1O N with their knee in the following configuration at an angle of B=60° with the horizontal. The foot is not touching the ground. Let the insertion of the patellar ligament be at a distance A=0.2 m from the knee joint O, the center of gravity of the leg at a distance B from O, and the foot at a distance of C from O. All distances are measured along the length of the leg. Let the weight of the leg be WL =40 N. Let B-4A and C=8A. Let the force in the patellar tendon Fm have a pull angle of 0=15° with the proximal tibia. (a) Draw an appropriate free body diagram of the problem. [provide your answer in your uploaded work]
