In my sophomore year MEAM Lab at Penn, our final project involved building and designing a bridge within a 10cm span. The bridge needed to be made from pressfit MDF. The goal was to maximize the strength-to-weight ratio and minimize the deflection. Our team of three, scored third among the 24 teams in the class. The video below shows the bridge testing apparatus using the load produced by the Instron machine, while the bottom picture is a Solidworks rendering of our bridge. An FEA analyses was also done on the bridge model in order to determine the maximum weight bearing load and resulting deflection and fracture point.
