3. Assume the upper arm is in the vertical position and the elbow is flexed 90 degrees, so that the hand and forearm are horizontal. Consider the hand and forearm to be a single rigid body. Find the elbow joint reaction force and elbow flexor muscle force when a 5 kg mass is held in the hand. Assume the elbow flexor muscles act along a single line of action originating on the humerus 28 cm from the joint center and inserting on the forearm & cm from the joint center. Assume the person is 1.8 m tall and has a mass of 80 kg.
