Hydraulics

Think liquids are wimpy? Think again! In this BrainPOP movie, Tim and Moby explain how some of the strongest machines in the world are powered by the liquid power of hydraulics. You’ll discover early examples of water-based engineering from Ancient Rome to medieval China. You’ll also explore how modern machines use pistons, tubes, highly-pressurized oil, and a nifty principle called Pascal’s Law to amplify their power. And you’ll see how all that power can be used to move the arms of huge construction vehicles or stop cars on a dime! Using liquid power to move mechanical monstrosities--now that’s a strong move.
