The design for the present bridge had to support a moving object, the truck. The difference that I had to account for was that the force being applied was different over time. Therefore there had to be a constant patter throughout the bridge and it had to be symmetrical. The use of triangles is evident in the design and they distribute the force appropriately. As the truck moved across the bridge the top beams recieved the most stress but held strong. One thing that could be improved is the strength of the top supports and to lower the weight of the material altogether. The estimated cost for this bridge is about 350,000 dollars. I do not forsee our group following this design because in the competition, the weight will remain stationary. Therefore, I predict that the new design, using kinects, will distribute the force from the center. I learned that to design a brige for a moving object is much more difficult than designing one for a stationary one.
