Structural Engineering - Bridges and Skyscrapers Dress-Up Extreme Dot to Dot: BabyDo 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
