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?

The fishing pole in Figure P10.22 makes an angle of 20.0 with the horizontal. What is the torque exerted by the fish about an axis perpendicular to the page and passing through the anglers hand if the fish pulls on the fishing line with a force F=100N at an angle 37.0 below the horizontal? The force is applied at a point 2.00 m from the anglers hands. Figure P10.22
