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. Each model demonstrates a basic principle of mechanical physics or structural engineering in a hands-on way.
A 44-page, full-color manual guides you through model building with step-by-step illustrated instructions.
