Bridging
As a near-final project for my engineering class, we got to engage in the time honored tradition of building balsa wood bridges. We were restricted to use wood no larger that 1/8 inch square and have a total bridge mass of under 30 grams. It took hours of laboring to produce this:
We loaded it up, and the bridge finally failed holding a total mass of 13 kg. Fully constructed, it weighed a measily 15.5 g, winding up with a total efficiency of 838 grams supported per gram of bridge weight. While this is by no means a world record, it was top of the class at least, and quite a bit of fun. I should have pictures of the destroyed bridge in a few days.
