1. The design goals for this particular bridge are to create a bridge that has the best price to weight  ratio. The bridge is a square shape with triangle reinforcements in order to create a design that is visually appealing and to allow for web members to be added in such a way that allows the load to be distributed evenly across the bridge.

5. The shape of the bridge was not changed much during the design, the hardest thing encountered was meeting the length requirement, many of the designs created were only 22" in length not the required 24". This led to problems when trying to find a design where the angles would work yet the length was sufficient. This design is certainly not the best work but without sitting in a lab and testing different designs there is no way take this bridge to the next level.

6. This assignment has shown that when working on designing something you need to have an image of what you want the design to look like going in so that you have something to work off of yet at the same time you need to keep an open mind in case problems arise. In this design problems arose that were unexpected such as trying to create a bridge that was long enough to span a 24" opening yet at the same time keeping in mind the fact that all connections must be made in increments of 45 degrees.
