  1. Balsa wood bridges are not capable of holding lots of weight but by their failure we can learn the weaknesses.

NOT TRUE. The strength to weight ratio for balsa is excellent. My company had a bridge building contest for engineers week. My bridge weighed 3.5 oz and held 718 pounds (2nd place). first plast was a little heavier and held over a thousand.

The best design depends on how the bridge is loaded, what dimensions must the bridge span and what restrictions there are (eg bridge weight and balsa stick restrictions).

  1. The best way to improve strength is by design.
