Hydraulic

Hydraulic fracturing makes use of high-pressure water to create cracks in hydrocarbon-bearing shale.

Because of hydraulic fracturing, used to extract natural gas, the earthquake risk for Oklahoma his risen exponentially and is now the same as for coastline from Alaska to California.

The Jet d'Eau fountain's name literally means "water jet" and was originally built to control and release excess pressure from a nearby hydraulic plant.

The hydraulic cylinder was the main problem and was changed to a new one.

Presently, prosthetics rely on relatively heavy hydraulic, electric or pneumatic actuators to flex artificial fingers, but scientists at Germany's Saarland University are experimenting with much lighter fibers made of a nickel-titanium alloy that change shape when connected to a source of electricity.

Tho' there are but seventeen feet water^([sic]) in the channel, I have seen vessels of five hundred ton enter into it. I know not why this entrance is left so neglected, as we are not in want of able engineers in France, in the hydraulic branch, a part of the mathematics to which I have most applyed^([sic]) myself.

A hydraulic press is operated by the differential pressure of water on pistons of different dimensions.
