Human Arm Model Without Sensors - ME-6807
Mechanical model that simulates the muscles and motion of an actual human arm.
Product Summary
The Human Arm Model simulates the muscles and motion of an actual human arm. This model does not include sensors. To order the model with sensors, see PS-2611. Students pull on the cord with a Force Sensor to activate the arm motion. Changes in position are measured at the shoulder and elbow using the two built-in potentiometers and the Angle Sensor (PS-2139). From this information, the torque applied when lifting an object can be determined. Students may also evaluate the work done by the arm when 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.
