Key Topic: Mechanics, Torque, Simple Harmonic Motion, Pressure

The Advanced Resistive Exercise Device, or ARED, is one of the exercise devices astronauts use aboard the International Space Station. ARED uses vacuum cylinders to simulate free weights for resistive exercise that helps astronauts maintain bone and muscle strength while in space. In this activity, students will analyze different aspects of the mechanics of the ARED device.

Students will
  • apply equations of pressure, force, torque, and harmonic motion to solve for unknowns;
  • draw a free-body diagram; and
  • analyze the design of exercise equipment used in space.
