1Discover the laws of nature that apply to bridges and tunnels.

The Science of Engineering series feature different forms of architecture and transport engineering. Features include funny and interesting illustrations; real-world science examples; side panels to tackle complex subject matter in a fun and relevant way; detailed glossary and more.Over time, scientists and engineers began to understand the laws of nature that apply to bridges and tunnels. They understood the strengths and weaknesses of materials better, too - and began to create new ones, like concrete and steel. This fascinating guide to bridges and tunnels explores unique examples of each, what they're made of, and all of the unexpected twists and turns taken in their development.
