The figure below shows a human arm that weighs 39.3 N. The arm
is extended outward and is motionless. The gravitational force
Fg
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
Fs
at point O, at an angle θ as shown. The
deltoid muscle pulls back on the...
