a person holds a 10.0kg weight in a forearm that is horizontal with the vertical upper arm. The biceps muscles exerts a force Fm distance of d=4.00cm at the elbow joint of horizontal forearm and the upper arm. The mass of the forearm is 1.10kg and its length from the elbow is 32.00cm. A)what is magnitude of muscle force Fm? B) what is magnitude and direction of force F on the forearm at the elbow joint? C) What is the magnitude and direction of force on the elbow joint by the forearm? Model this as an uniform rod
