The amount of power that hydraulic pressure can exert made hydraulic based machinery a massive success among several industries, businesses and even individuals. Today, a widespread application of hydraulic machines can be seen affecting every life in some or the other way. It is basically a very simple medium which uses a comparatively cheap source of power, i.e. liquid and creates immense power out of it, if not more than that of steam or electricity, at least is several times cheaper and convenient to use. A fine example of such machinery would be a hydraulic jack which has two cylinders attached with liquid fluid in one and a piston in the other to create power. The normal screw jack has been replaced by the hydraulic counterpart of it because of its high efficiency and ease of operation.
There are several machines which use hydraulics system to exert power including the giant excavators, mobile crane, or other load sensing systems, all working on the simple, yet powerful principle of Pascal’s law invented by a Scottish engineer.
Some other devices which use the same mechanism are hydraulic toe jacks, furniture movers, machine movers, load moving skates and many others which contribute to each of our lives directly or indirectly like helping in creation of wonderful structures and buildings.
