Torque Challenge

Force & Mechanics

★Exhibit Content: Lever Principle ★Interaction: Mechanical Interaction ★Operation: 1. This exhibit requires two people to compete. Each holds a different disc and twists in opposite directions to see who is stronger. 2. Swap the disc positions and try again! ★Exhibit Description: The exhibit consists of a base, a rotating shaft, and discs, demonstrating a wheel and axle. The wheel and axle is a simple lever-type machine, where the wheel and axle rotate around the same axis. ★Scientific Principle: The wheel and axle is a modified lever. The axle center acts as the fulcrum, and the radius of the disc is the lever arm. According to the lever principle, effort multiplied by effort arm equals load multiplied by load arm. If the effort arm is several times the load arm, the effort is a fraction of the load. Since the radius of the large disc is greater than that of the small disc, a relatively small force can achieve twice the result with half the effort.
