Im building a balsa bridge for class but I'm struggling to find a design. The bridge must hold 20 pounds and have a trapezoid clearance. the minimum length is 14cm and the max is 20cm, min to max height is 5-8cm. Width must be 3cm. Here is my design so far, I would build two of these faces and connect them with horizontal lengths of balsa. I have 24 feet of balsa so please critique, advise, and even reconstruct my design. Thanks(adsbygoogle = window.adsbygoogle || []).push({});
