Bridge Write Up The problem that we have is we need to find a bridge that will fill a gap that is 12" long‚ and 2.5" wide. Our objective is to build a bridge that can hold up to 2.5kg at the most. The bridge must have a length at least 3inches‚ and a width of 2.5inches. Some constraints that we have are no more than 10% of the bridge may consist of "bulky" members made from two pieces of balsa wood. We can only use 15 pieces of balsa wood‚ and if we use string it has to be attached in a simple
