Bridge project

Lately I have been working in a group with Callan on a bridge project. Our question was which bridge design could hold the most weight. The bridges we chose were the beam bridge, warren truss bridge and the deck truss bridge. Our hypothesis is that the deck truss bridge will be able to hold the most weight and that the beam bridge will be able to hold the least weight. At the moment we are up to the eperiment stage of our project.
