My partner and i are going to use different materials to make tons of bridges. We have it all planed out, but we need a hypothesis. And our hypothesis has to be based on research. If anyone can help, please do. Answers or website addresses would be great.

The funny side of life is they dont teach these in colleges. What you need to do is look for bridges in a site and keep searching till you come out with a good lot of literature.
The problem with bridges is you have different types depending upon the terrain, climatic conditions and countires.

Fun with bridges starts here. Imagine a complex girder bridge. The sort that looks like a lot of letter "W" and "M" all hooked together. A "cantilever" bridge. Now focus your attention on any single joint in the structure. As many as 7 or so girders come together there. Question: what is the total sum of the force at that joint? You don't need any details. The answer is this: zero. If there were any total sum force there, then from ole physics F = MA, the joint would be accelerating and the Brooklyn bridge wold be in Tampa or something. So, since it still in Brooklyn, you know that the sum (and this is the vector sum) of all the forces must be zero.
