Detailed explanation-1: -The principle was first enunciated by the French scientist Blaise Pascal. Pressure is equal to the force divided by the area on which it acts. According to Pascal’s principle, in a hydraulic system a pressure exerted on a piston produces an equal increase in pressure on another piston in the system.
Detailed explanation-2: -The hydraulic system works on the principle of Pascal’s law which says that the pressure in an enclosed fluid is uniform in all the directions.
Detailed explanation-3: -Automobile Hydraulic Lift A hydraulic lift for automobiles is an example of a force multiplied by hydraulic press, based on Pascal’s principle. The fluid in the small cylinder must be moved much further than the distance the car is lifted.
Detailed explanation-4: -Equipment such as cranes, forklifts, jacks, pumps and fall arrest safety harnesses use hydraulics to lift and lower objects. Airplanes. They use hydraulic mechanisms to operate their control panels. Amusement park rides.
