9. [12 Points] DETAILS MY NOTES 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 force at in the deltoid muscle and the force Es 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.) N N ii Submit Answer 10. [-13 Points] DETAILS MY NOTES ASK YOUR TEACHER A person is standing on a section of uniform scaffolding as shown in the gure. The section of scaffolding is L = 1.50 m in length, has a ms = 22.0 kg mass and is supported by three ropes as shown.
