I need a bit of help here. I have an upcoming assessment towards bridge design. The task is to create and construct a bridge made out of dried spaghetti sticks. The bridge is to be as light as possible while holding the most weight. I currently have 1 main design I'm leaning towards, but I'm unsure that it would be successful. I don't want to construct the bridge to find out it collapses on me. http://img172.imageshack.us/img172/9060/bridgeif7.png [Broken] I beleive that the triangle, upside down would serve me better. Though I'm still unsure about the whole design of it. I just basically want to know if this would be an idealistic plan to making a bridge, or if any other designs could easily top mine. The KEY guidelines are below, in which the bridge must follow. Key Guidelines: - The span of the bridge cannot exceed 648mm - The roadway (width) of the bridge must equal roughly 80mm - The bridge must NOT exceed 1000g If anyone can offer advice about my plan, it would be highly appreciated.
