Join us for our next competition, to be held this Sunday! The process of building small bridges involves taking small individual pieces sticks of balsa wood, modifying end points to fit the chosen design carefully gluing the pieces one to another until the fully functional bridge framework is created.

While the bridges can also be created from smaller, lightweight and easily manageable building materials such as toothpicks or popsicle sticks, bridges created using balsa wood are much more durable and versatile.

Balsa Wood Bridge - How to Build a Strong Balsa Wood Bridge

Advanced bridges are usually focused on designs based on arched, cantilever and bowstring bridges. With a bottom truss design, the bridge is weighted down by all of the trusses that reach downward. The increase in height also decreases the load of the bridge, and when the load is decreased, then the bridge can be taller. The process of building small bridges involves taking small individual pieces sticks of balsa wood, modifying end points to fit the chosen design carefully gluing the pieces one to another until the fully functional bridge framework is created.

However since there is so much variety between each competition, students are often instructed to comply with a vast array of additional challenges, restrictions, and rules. If you are making your bridge for a competition, be ready to see it break. The bridge may touch the top or inner surfaces of the supporting planks, but may not touch any other surface, nor be affixed to any surface.
Description:Therefore, it is unlikely that my bridge design will be able to be completed with just ten pieces of balsa wood. Because of this added layer of complexity, bridge building projects that are done before high school are usually not utilizing balsa wood. For a bridge that is at least eleven inches long, then it needs to be at least one-and-a-half inches tall. The load plate is 10 x 5 x 1 cm, and has a loading hook extending from the center of the bottom surface which requires 1 cm annular clearance through and below the bridge deck. The bridge building is also used extensively as a tool that can guide students to understand the desired subject area better, learn more about structural design or the process of building bridge structures. While some of the bridges are created during the regular school curriculum in high schools and colleges, much more popular application of this technology can be found in various competitions that bring together not only contestants from various schools but also hobbyist and engineers who want to be challenged by the various restrictions and challenges.
