Question

explain the principle of a hydraulic machine. Name two devices which work on this principle.​

Answer 1

Answer:

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. ... As the pressure is same in all the direction, the smaller piston feels a smaller force and a large piston feels a large force.

Answer 2

The principle of hydraulic machine is that a small force applied on a small piston is converted to generate a large force on the bigger piston.

Two devices that work on this principle are:-

• hydraulic brakes
• hydraulic press
