The figure below shows a human arm that weighs 39.0 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 Fg 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. 0.080 m 0.290 m Find the magnitudes (in N) of the forces F, and F.

the figure shows a horizontal human arm lifting a dumbbell. the forearm is in equilibrium under the action of the weight w of the dumbbell, the tension t in the tendon connected to the biceps muscle, and the force e exerted on the forearm by the upper arm at the elbow joints. we neglect the weight of the forearm itself. (for clarity, the point a where the tendon is attached is drawn farther from the elbow than its actual position.) given the weight w and the angle between the tension force and the horizontal, find t and the two components of ē (three unknown scalar quantities in all)
