The upper leg muscle (quadriceps) exerts a force of 1220 N, which is carried by a tendon over the kneecap (the patella) at the angles shown in Figure 5.43. Find the magnitude and direction of the force exerted by the kneecap on the upper leg bone (the femur).____N_____o (counter-clockwise from an axis directed to the left) This image depicts a diagram of the human knee joint, illustrating the forces and angles involved in its mechanics. - The femur (thigh bone) is shown at the top, connecting to the tibia (shin bone) at the bottom.- Two angles are marked on the diagram: 55° and 75°, indicating the degrees of flexion at different points of the joint.- An arrow labeled \( F_o \) is pointing downward along the tibia, representing the force exerted by the quadriceps muscle.- Another arrow labeled \( F_c \) points upward along the femur, indicating the force exerted by the patellar tendon.- The diagram also shows muscle fibers positioned at an angle to the femur, illustrating the muscle's line of action.The diagram highlights the biomechanics of the knee, demonstrating how forces are transmitted across the joint during bending and movement.
