How a tiny pump can lift a bulldozer

A closer look

Construction equipment bullies massive boulders just by aggressively squeezing thick fluid through tiny tubes. Because oil cannot be compressed into a smaller volume, forcefully pushing a small piston down instantly forces the fluid to shove a much wider piston upward. This fundamental fluid tradeoff beautifully converts a small pump's stroke into enough sheer mechanical lifting force to raise an entire bulldozer bucket.
