Question:

The drawing shows a lower leg being exercised. It has a 49-N weight attached to the foot and is extended at an angle u with respect to the vertical. Consider a rotational axis at the knee.

(a) When u 5 90.08, find the magnitude of the torque that the weight creates.

(b) At what angle u does the magnitude of the torque equal 15 N • m?
