Short Desciption:
Principle Used in Hydraulic Actuator System ..hydraulic actuator is highly incompressible so that pressure applied can be ..... Ans: Immediately the pressure difference across the hydraulic cylinder

Summary:
Hydraulic Actuators, as used in industrial process control, employ hydraulic pressure to drive an output member. These are used where high speed and large forces are required. The fluid used in hydraulic actuator is highly incompressible so that pressure applied can be transmitted instantaneously to the member attached to it.

It was not, however, until the 17th century that the branch of hydraulics with which we are to be concerned first came into use. Based upon a principle discovered by the French scientist Pascal, it relates to the use of confined fluids in transmitting power, multiplying force and modifying motions.

Then, in the early stages of the industrial revolution, a British mechanic named Joseph Bramah utilized Pascalís discovery in developing a hydraulic press. Bramah decided that, if a small force on a small area would create a proportionally larger force on a larger area, the only limit to the force a machine can exert is the area to which the pressure is applied.
