3. A patient is learning to use a wheelchair for the first time, and you are interested in how efficiently he is able to propel himself. On his first day in the wheelchair, you recorded the forces that he applied to the right wheel each time he pushed on the wheel to propel himself down the hall. Two weeks later, you recorded the forces again. Below are illustrations of the averages of these forces for each session. Assuming that the magnitude of the average push force was the same for each session(i.e.152N), how much propulsive torque was generated by each push? (Assume the radius of the wheel is 0.25m, make sure the direction of your torque is correct)

Session 1 F=152N, θ=38.5°

Session 2 F=152N, θ=22.6°
