Topic > The construction and design of a bridge - 700

Our task was to build a bridge, but not only that, it was to build an efficient bridge. To be an efficient bridge it had to support more weight than it weighed. We had to be able to design and build our own bridge. Both had to be good, because if either was bad, our bridge would not be efficient. Not only did we have to do it, but we were required to comply with many constraints and rules. The hardest challenge for me was that there were so many variables I couldn't account for; this was my first time building something like this. There was also another underlying challenge that came with this project; it was about finding out whether you were able to work well with a partner and whether you were capable of choosing a good partner. The challenges were complex in a way, on the surface they seemed simple, but in reality they were much harder than expected. When I started designing my own bridge, I started thinking about bridges I had seen in person. That didn't go so well, with my memory vague and the bridges that came to mind were absolutely impossible to build, I went to the Internet. I managed to find the three main bridge designs; the Pratt, the Howe and the Warren. From what I saw I decided that the Howe Bridge was more structurally sound. So we used it as the basis of our idea/design. We added our own flare by dispersing vertical supports throughout our structure. We had decided to make the side and our deck with balsa wood and the bottom with Popsicle. We wanted to strengthen the bottom, so we turned the popsicle stick on its side, because it was stronger that way. With our project in hand we were able to calculate the total weight of our structure, which turned out to be b... half the paper... over a hundred kilos we achieved one of the best efficiencies with our bridge holding the most fourteen hundred times its weight. Our efficiency has proven to be one of the best in the category. We faced this challenge head on. We worked efficiently with each other, which paid off because we had great efficiency. I really liked this project, it was a nice introduction to the other projects we will have. It gave me a nice insight into where my skill level might be in this type of thing. I have some suggestions on how this project could be better for future students, since this is an introductory project, I should say there shouldn't have been so many constraints. You should also try to let students choose the type of material they want. All in all, this was a very fun and informative introductory project to this class.
