Biomedical applications 1. Imagine you are at the gym exercising your hamstring muscle (the large muscle in the back of your thigh). You lie prone (i.e. on your stomach) on a bench and use an elastic cord attached to a hook on the upright position of the apparatus while keeping your leg in a bent position (see figure). If you pull with you lower leg such that you exert a 90 N force on the cord attached to your ankle, determine both 1) the magnitude of the tension force of your hamstring on your tibia (shin bone; your hamstring is attached to the tibia roughly 1.5 inches away from the your knee) and 2) the compression force at your knee joint exerted by your femur on your fibula.
