The objective of this project was to create a physical model to demonstrate the transfer of forces from the mechanical, hydraulic, and back to the mechanical domains. To do this, a spinning wheel was designed to be stopped using a hand brake connected hydraulically to a set of calipers and a brake rotor. A wheel on a dead axle was spun up via a motor and once the wheel was at speed, mechanical force was applied to the hand brake to bring the wheel to a stop. Once all the calculations ensured that the model would not fail during operation, a physical model was constructed. The final model successfully shows the transfer of mechanical force to hydraulic force to mechanical force, which generates friction between the calipers and the brake rotor to stop a rotating wheel.
