The figure represents the slow flexion and extension movements of the leg and thigh. the length of the leg is L=0,4m, and the weight of the leg is m=4.8Kg, and the thigh m=9,8Kg. We´re also given the distances to the center of mass of the thigh (B) and leg (D) from the extremities. ( AB= CD= 0.43L ).
Determine the force F in function to angle alfa, and the strength of the joint connections of the hip(A), the knee(C) and the ankle(E).
