As the bicep muscle cord is pulled a short distance, the end of the arm moves through a very large distance, showing the mechanical advantage of the arm. The load at the end of the arm can be varied.

As the tricep muscle cord is pulled with a Force Sensor, another fixed Force Sensor records the tension in the bicep muscle cord.



As the bicep muscle cord is pulled a short distance, the end of the arm moves through a very large distance, showing the mechanical advantage of the arm. The load at the end of the arm can be varied.

To perform this motion, an elastic cord is used as the bicep muscle cord and the tricep muscle cord are pulled with a Force Sensor. The motion of the arm and the release speed of the ball are measured with the built-in potentiometers using the Angle Sensor.










Mechanical model that simulates the muscles and motion of an actual human arm. To activate the motion students pull on the cord.

Product Summary
The Human Arm Model simulates the muscles and motion of an actual human arm. To activate the arm motion, students pull on the cord with a Force Sensor. Changes in position are measured at the shoulder and elbow using the two built-in potentiometers plugged into one Angle Sensor (PS-2139), included with PS-2611. From this information, the torque applied when lifting an object can be determined. Also, students can evaluate the work done by the arm in throwing a ball and the resulting kinetic energy delivered to the ball.
The Arm can perform many types of motion such as extending and lifting an object, curling, or throwing a ball overhand. Different arm muscles are activated depending on which pulleys are selected. Static force measurements can also be made to see how the muscle tension changes at various arm positions.
