Do you ever wonder how bridges span huge distances and how skyscrapers stay standing. Structural engineers use physics and their knowledge of the properties of building materials and geometric shapes to design structures with sufficient strength and stability. With this kit of modular building pieces, you can learn the basics of structural engineering by conducting a series of 20 model building experiments. Start out with small models that demonstrate how structural elements can be attached together to maximize the strength of a structure for a fixed amount of material used. Move onto building more complex models of trusses, roofs, and small buildings. Experiment with different types of bridge construction a truss bridge, arch bridge, cantilever bridge, rope bridge, and suspension bridge. Finally, build models of towering skyscrapers. Learn about the strength and stiffness of materials see how structural engineers optimize factors to maximize safety, and minimize cost and the risk of structural failure.
