Question
**Diagram and Scenario Description:** - The image shows a young girl holding her arm straight out parallel to the ground. - Her arm is perfectly straight, with the shoulder acting as the pivot point. - The diagram includes: - An indication that the angle between the deltoid muscle and the arm is 15 degrees. - A measurement from the shoulder to the deltoid force point at 17 cm. - A measurement from the shoulder to the hand at 38 cm. **Problem Statement:** A young girl is holding her arm straight out parallel to the ground. Her arm is perfectly straight. Use the information given in the picture and below to solve problem 2. a) Draw and label the free body diagram of all forces on the shoulder. b) Calculate the force of the deltoid using the sum of the moments. c) Find the vertical reaction force of the shoulder. Is it acting "up" or "down"? Weight of the arm = 1 kg
