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 Marrowbold perpendicular to the arm, as the drawing indicates. The forearm weighs 20.0 N and has a center of gravity as indicated. The scale registers 122 N. Determine the magnitude of Marrowbold.
