Human Arm Model (Room S-212) Goal: To predict and then test, the forces exerted by the biceps muscle for various conditions. General Approach: 1. We will lift masses using a student’s biceps (curl) and make predictions of the forces exerted under various conditions. 2. We will use the human arm model to measure the forces involved. 2015 11-1
Experimental Outline I. Biceps Force vs. Perpendicular Load Predictions : Hold your arm in front of you, with your elbow bent at 90°. Now have your partner pull your hand down in an attempt to straighten your arm. Resist the force so that your elbow remains at 90°. 1. Was your muscle force greater than, less than, or equal to the force applied to your hand? 2. If your partner pulls down with a force of 1.0 N, guess how much muscle force is needed to keep your elbow at 90°. Procedure: 1. Lock the shoulder of the arm model apparatus at 0°. 2. Open the Capstone software as instructed by lab instructor.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
