Building Basics
What stops a skyscraper from falling down and a giant bridge from collapsing? This BrainPOP UK movie won’t answer those particular questions, but it will show you some basic building techniques. In this educational, animated movie you’ll learn how all structures, no matter what their size, must work with the forces of gravity, tension and compression, in order to stay up. You’ll see how the simple post and lintel technique was used to build Stonehenge and you’ll find out the reason the ancient pyramids are still as strong as ever. Now, where’s that Lego? |
