In an isometric 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, because the figure indicates. The forearm weighs 19.3 N and has a center of gravity as indicated. The scale registers 130 N. Decide the magnitude of.
