1. The problem statement, all variables and given/known data The drawing shows a lower leg being exercised. It has a 49 N weight attached to the foot and is extended at an angle θ with respect to the vertical. Consider a rotational axis at the knee. a. When o θ = 90.0 , find the magnitude of the torque that the weight creates 2. Relevant equations 3. The attempt at a solution Shouldn't the angle be the force (weight) with respect to r? Here is r with respect to r perpendicular, or did I get the labels wrong? If it is the case, should we solve the angle by 90 - theta? I get the answer but I dont get the concept. Can someone help me with the labelling? Great appreciated if you can explain it on the diagram, thanks!
