Our main project was to create a bridge that is efficient in sustaining a lot weight compared to the the actual weight of the bridge. We would end up taking it to the MESA Day competition that is held annually at CSU East Bay. We started off by designing our specific bridge on a program known as white box. On it we learned about the math that goes into building a bridge, how the engineering helps us to not have collapsing bridges. When it finally came time to building it, we used balsa wood for its low weight and high strength. We were only allowed to use Elmers glue to sustain our pieces of balsa together. Our bridge in the overall design ended up weighing 54 grams and held around 91 pounds.
