Gear Motion Physical Model
Built and assembled a gear-driven physical model for a dynamics hardware assignment in BYU's ME EN 204 course. The project focused on understanding how gears and linked motion systems transfer movement through a mechanism. It demonstrates hands-on mechanical intuition, assembly, and translating course concepts into a tangible model.
Overview
This was a BYU ME EN 204: Dynamics physical-hardware model project. The assignment was to build a model incorporating four-bar linkages and/or gears.
I used a ROKR Magic Piano Music Box as the basis for the demonstration model.
Timeline
- Duration: December 2024
- Total time: 5 hours
Results
The final product took about five hours to assemble and included both a functional music box and working gear motion.
