Draw a FBD of a person who is holding a 9 pound weight in her hand. Her shoulder is
abducted to 90o, her forearm is fully extended and her wrist is at neutral. The weight of her upper extremity (UE) is 11.1 pounds. The center of gravity of the 9 pound weight is 22.5 inches from the axis of rotation. The center of gravity of her UE is 8.75 inches distal to the axis of rotation. The deltoid muscle, which is attached 4.8 inches distal to the axis of rotation, is providing the force to maintain the abducted position of the UE.

2. A person is holding a weight (100 N) in their hand. The weight is a distance of 0.3 meters from the center of rotation of the elbow. If the forearm is parallel to the ground, what is the torque about the elbow due to the weight? If the forearm has an angle of 30° above the horizontal (hand is higher than elbow), what is the torque about the elbow due to the weight? c. If an elbow flexor muscle...
