<br/><br/> Design and build an 8-foot beam bridge capable of carrying a swarm of pedestrians across a small stream. First, consider three alternative concepts, with beams made of identical wood, but of different configurations. Then develop these designs, analyzing their stresses and failure modes before selecting the optimum, building it, and inviting your friends onto the span.
