In an isometric exercise a person places a hand on a scale and pushes vertically downward, keeping the forearm horizontal (please see attachment). This is possible because the triceps muscle applies an upward force M perpendicular to the arm, as the drawing indicates. The forearm weighs 25.0 N and has a center of gravity as indicated. The scale registers 112 N. Determine the magnitude of M.
