The figure below shows a human arm that weighs 39.6 N. The arm is extended outward and is motionless. The gravitational force F on the arm acts at point A, a distance of 0.290 m from the shoulder joint, which is represented by point O. The shoulder pushes down and to the right on the humerus bone of the arm with a force F at point O, at an angle 0 as shown. The deltoid muscle pulls back on the arm toward the shoulder with a tension force F. This tension force acts at a point 0.080 m to the right of point O, and it is directed up and to the left, at a 12.0 angle with respect to the horizontal. 120 O F 0.080 m 0.290 m Find the magnitudes (in N) of the forces F, and F . (Enter your answers to the nearest whole number. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) 477.11 X What is the equilibrium condition for the net torque on the arm? Which pivot point should you choose to have only one unknown force? What is the magnitude and direction of the torque due to F.? Of the torque due to F ? N F 124.15 X What is the equilibrium condition for the net force? Apply this condition to both the x- and y-components of the forces. Can you find the x- and y-components of F ? From the components, what is the magnitude? N
