My Bridge

When constructing my bridge I plan to produce a relatively basic truss bridge. By studying other successful balsa wood bridges on balsabridge.com I have found that the best bridges utilize either a truss or a piece of circular bent wood acting as a different type of truss. I decided to go with a truss because I believe that it is a slightly more basic structure type to understand and that it will be easier to construct. I took how easy the bridge was to construct into consideration because I wanted to try to decrease the percentage of error of my bridge failing as much as I possibly could. The design of my bridge looks much like this design:

I feel like this design was one of the best designs for constructing a balsa wood bridge because this is a strong truss design which will distribute the force that is applied by the weight nicely. In addition, this truss design is one that does not have an upright beam that is located at the midpoint of the bridge. This makes this design one that can be used for this particular project because if it were to have that upright beam at the midpoint then the metal rod that suspends the weight would not be able to be placed there.
