Bridges Built to Last

Overview

I tested the strength of three types of bridges (Truss, Beam and Arch) I designed and 3D printed four of each bridge type, attached buckets with a testing rig and put sand and weights inside until each bridge broke then I weighed each bucket and recorded the weight. The result of my work showed that the truss bridge was the strongest and the beam bridge was the weakest. This taught me that even on a small scale bridges can hold a lot of weight. It is important to understand how the design and structure affect how much weight it would take each bridge type to fail.
