What is hydraulicing?

Answer 1

Hydraulics is the term we apply to engineering compressed liquids. The industry frequently applies the term fluid power to hydraulics, though it is a bit of a misnomer as fluids include gases. Gases are compressible, while liquids are largely incompressible. In hydraulics, some sort of pump or compressor will pressurize the liquid (which is quite often hydraulic fluid) to add energy to it so that the fluid can be used to operate rams or drive fluid powered motors. The trash trucks that dump those big containers use hydraulic power, as do the big cement mixers, which use it turn the mixing container to keep the concrete in motion. Wikipedia has a nice article on hydraulics, and a link to their post is provided. You'll find that link below.
