For our Honors Freshmen Physics class, we have been assigned to create a balsa wood bridge. This bridge has to be no heavier than 100 grams, with the length around 17 and a half inches, with an inner roadway of at least 3 and a half inches wide. The bridge also cannot have anything wider than 1 inch and it cannot be more than 1/4 of an inch thick. In order to get an A, I have to create a bridge with the requirements above and it must hold at least 120 pounds. For my bridge, I have chosen to build a bridge like the one shown in the diagram above. It is a simple, truss bridge shape that I have looked over and researched to make the best result possible. I have chosen this design for my bridge because it is simple, yet powerful. At this point in time, my bridge is still under construction, but right now it seems to look pretty strong. All in all, I have chosen this simple, yet effective design for my bridge.
