My idea for designing the bridge is to use small pieces, such as the blue and white beams, so that I can include more numbers of pieces for a low estimated total cost. My design contains square cross sections, which holds triangular webs to provide the strongest support. Design 1 contains a strong web, but is a expensive bridge while Design 2 has weak webs for a low cost. During the designing process, I changed various aspects of the bridge, such as making the bridge smaller by using the blue bars instead of yellow bars for the outside frame. In addition, I changed the design of the web several times in order to create a very inexpensive bridge. In conclusion, I was able to receive experience on how to use the Knex pieces to design a bridge. It was a very good experience because it was much different than using West Point Bridge Design and required more critical thinking. In addition, I learned how to design a bridge by keeping the cost in consideration, which will be of huge importance during the competition.
