Bridge Design
Define a Problem
In this project, we were to create a bridge that would withstand a simulated test. The goal was for a truck to be able to cross it without the bridge falling down. The bridge had to cost less than $400,000, have no more than 50 joints and 120 members, and hold the 480Kn truck.

In this project, I learned lots about the general topic of engineering. We had to figure out a design that would work just right and doing this was no easy task. The process of trying and failing over and over again got me frustrated, but i learned from it. Taking away more knowledge on which designs work or not, weight distribution, and how bridges are designed in general.
The way the weight was put onto the bridge created mostly tension and compression. The truck pushed down on the bridge and depending on how the members and joints were arranged, were put under tension and compression and the vehicle drove across.
Though compression and tension forces work opposite of each other, the forces can be cancelled out and redirected to be sturdy and hold weight by a system of members and joints.
