Hydraulics is a branch of science with the applications of fluid usually liquids in motion. Hydraulics deals with matters such as flow of liquid in pipes, rivers, and channels and their confinement by dams and tanks. Liquids in motion or pressure did useful work for man before Blaise Pascal and Daniel Bernoulli formulated laws for hydraulic-power technology. Pascalś law which was created in 1650 states that pressure in a liquid is transmitted equally in all directions. In the hydraulic press Pascal's law is used to increase force. A small force applied to a small piston in a small cylinder is transmitted through a tube to a large cylinder where it then presses equally against all sides of the cylinder including the large piston. Until the 19th century it was not possible to develop velocities and pressures much greater than those already provided by nature. In hydraulic-power systems there are five different elements: the driver, the pump, the control valves, the motor, and load. The driver may be an electric motor or any type of engine and the pump acts to increase pressure.The motor may be a counterpart to the pump and motors may produce either rotary or reciprocating motion in the load. A hydraulic press, is a device …show more content…

Liquid is used to move objects as it is incompressible than per say air. As liquid is incompressible applying a force to one end of a hydraulic system transmits the force through the liquid to the other end.A hydraulic system is made up of a liquid-filled tube topped with two pistons. Applying a downward force on the closed system would cause the liquid to move against the opposite piston and due to liquid being incompressible the piston pushed upwards. The advantage of hydraulic tools is the concept of force multiplication. Force multiplication allows the force you apply to one piston to be multiplied, by multiplicative factor, to make a larger force acting on the second
