A person is performing a knee extension exercise with a 100 N weight acting at the ankle. What is the torque at the knee necessary to maintain a knee joint angle of -60q relative to the right horizontal passing through the knee joint? Weight of lower leg and foot = 10 N; center of mass of lower leg and foot located 0.15 m from the knee joint and weight located 0.4m from the knee joint.
