. [112 Points] PREVIOUS ANSWERS ASK YOUR TEACHER The arm in the gure below weighs 43.6 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension at at force Ft in the deltoid muscle and the force FS exerted by the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown. (Enter your answers to at least the nearest newton.) a=_~ _x Your response differs signicantly from the correct answer. Rework your solution from the beginning and check each step carefully. N F5 Since there are 2 unknown forces, it's going to help if you put the pivot on top of one of those forces. This will remove a term from your torque equation and allow you to solve this problem more easily. Submit
