Summary:
Bridges are needed to cross railroad tracks, rivers and highways. They are an important part of the transportation infrastructure of any country. Bridges must be strong enough for trains that pull heavy cargo cars. This project tests the strength of three different bridge structures. The three bridge types investigated include the plank bridge, truss bridge, and suspension bridge. The bridges are fun to build and test.
