Physics' way of letting a toddler-weak push lift a truck.
means The branch of engineering that uses liquid under pressure to transmit force and power machinery.
from From Greek 'hydraulikos,' meaning 'of a water organ,' built from 'hydor' (water) and 'aulos' (pipe or flute). The ancient reference was literally to a water-powered pipe organ — the pressure principle was first noticed making music before it ever lifted a truck.
- core principle
- pressure applied anywhere transmits equally through the fluid
- secret ingredient
- liquids barely compress, so force transfers almost losslessly
- everyday proof
- car brakes amplify your foot into tons of force
- ancient cousin
- Pascal formalized it, but Egyptians used it for dams
