Reference no: EM13651031

In an is ometric exercise a person places a hand on a scale and pushes vertically downward, keeping the forearm horizontal. This is possible because the triceps muscle applies an upward force perpendicular to the arm, as the figure indicates. The forearm weighs 20.7 N and has a center of gravity asindicated. The scale registers 113 N. Determine the magnitude of.
