Here is a short, fun video showing creative bridge designs from very limited supplies. These bridges were required to be under 5oz in weight, but only had to span 8 inches. I like this video because it is pretty clear why each bridge failed. Can you see a major design issue that could be improved in most of these bridges? Notice that they do incorporate triangles, but they are missing a key member. The students were only given Cardstock Rubber […]
The Bridge Designer is perhaps the greatest online tool for building model bridges. It allows you to design a virtual truss, put a load on in, and it calculates how the forces are spread out. Amazing.
All the time I am asked “How tall should I make my bridge?” This article will attempt to answer this question by illustrating a principle in model bridge building. There is no cut and dry answer, as you should evaluate your bridge specifications and guidelines and conduct experiments to reach the best answer for you. How Changing Height Affects a Bridge This is our control bridge. The bridge is 8 inches long and 3 inches tall. I have added two […]
Recently I was introduced to a bridge building program, Bridge It. This program is made by NVIDIA and Auran.

Bridge It lets you build these bridges from a variety of materials, including suspension cables. The bridges are tested by a car or train, and sometimes by […]
The type of joint you use on your bridge can drastically change its strength. There are three basic types of joints, the Lap Joint, End Joint, and Notched Joint. To increase the strength of an end or notched joint you can add a Gusset. Learn about each type of joint and when to use it on a model bridge in this article.
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.
This is a great book to learn about bridges, how they work and how to build them. Designed for grades 2-6, this book contains arch bridges, beam bridges, and suspension bridges. Included are activities and challenges to think outside the box. This is a great resource for children who want to understand more about bridges
This is a free bridge builder game that I found and it is pretty neat. Construct a bridge and test your building skills. Help your people gather items located on the other side of valley.
