What is a bridge? A bridge could be anything as simple as a log laying across a creek. Or as sophisticated as the Golden Gate Bridge. A bridge is just something that helps us cross an obstacle, whether that be a river, ocean, swamp, canyon, or highway. At the most basic level, there are three types of bridges: Beam, Arch, and Suspension.

I like this video because it is pretty clear why each bridge failed. Can you see a major design issue that could be improved … Read more Bridge Contest from Junk Yard Wars
Balsa wood is unique from all other woods. Its properties make it valuable to bridge builders, wood carvers, surfers, and many others. Bridge builders have to be careful, however, when using Balsa. You can’t simply pick up two pieces of Balsa with the same dimensions and expect them to perform the same.
The Arizona Science Lab presents information on types of beams used for building bridges. They show the huge difference in resistance to bending between a flat beam and an I Beam. Then different types of truss designs are shown and explained. Afterwords the students are given supplies to build their own bridges, and this video … Read more ASL Bridges Class, Feb, 2012
