**Problem 15** A person exerts a horizontal force of 190 N in the test apparatus shown in the drawing. Find the horizontal force \( \mathbf{M} \) (magnitude and direction) that his flexor muscle exerts on his forearm. **Diagram Explanation:** - The diagram shows a bent arm with a force gauge attached at the wrist, exerting a horizontal force of 190 N. - The distance from the elbow joint to where the force is applied is 0.34 meters. - The flexor muscle is indicated, exerting its force \( \mathbf{M} \) at a distance of 0.054 meters from the elbow joint. - The muscle's force is directed horizontally, opposing the external force applied at the wrist.
