Project 1: Form and Function

I designed and constructed a model bridge featuring a 30" x 40" roadbed that can open and close. The bridge uses a mechanical tool to control the movement, allowing the roadbed to lift and return smoothly. This project demonstrates an understanding of basic engineering concepts, structural design, and mechanical motion systems.
