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 M perpendicular to the arm. The forearm weighs 20.1 N and has a center of gravity. The scale registers 116 N. Determine the magnitude of M. The distance from M and the elbow joint is .025m, from the elbow joint to the forearm is .150m, and from the elbow joint to the scale is .300m. Thanks so much!
PLEASE HELP ME WITH THIS PHYSICS PROBLEM!!!! AHHHH?
