Conflict: Make a bridge that has a sustainable hold weight. First, we researched what kind of bridge we wanted, this is our first prototype. By adding some supports to the top and sides, my next prototype held more. My next improved prototype held 17 LBS. This bridge held 14 LBS.
Develop Ideas I first started to think to build a Truss Bridge. Then I tried a tall dome shaped bridge
Then I decided to use this bridge to test because it was easier to build, toke less wood, and would be strong
Then I tested it and it held 48 pounds
