One person was doing a knee extensor muscle training, he used a dumbbell (mass = 10.2 kg) strapped to the ankle joint and was 0.4 m from the knee joint (see attached figure). The dumbbell was 0.3 m away from the knee joint in the horizontal direction. How large was the torque generated by the dumbbell weight about his knee joint?
