Human Arm Model

Demonstrate and measure the forces at work inside the human arm

  • » Students see what happens when they throw a ball

Human Arm Model  (PS-2611)

Human Arm Model free throw

FREE THROW - Measure the work done by the arm and the resulting kinetic energy delivered to the ball during a free throw.

Human Arm Screen Shot Human Arm Extension

EXTENSION - This graph captures the sharp increase in the tension (force) of the bicep muscle as the arm is fully extended. The tricep muscle cord is pulled with a Force Sensor, while a second Force Sensor measures the tension on the bicep muscle cord.

The Human Arm Model simulates the muscles and motion of an actual human arm. Full range of motion including throwing, curling and extension can be measured.

  • Capture muscle tension, shoulder and elbow joint movement data
  • Measure force and angle simultaneously
  • Link tricep and bicep muscle action to arm motion
Human Arm Model curl

CURL - 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.

Pull on a rope with a Force Sensor to activate arm motion, and measure both muscle tension and shoulder and elbow joint rotation. The Human Arm Model 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.
