Question

How do hydraulic machines work? On what principle?

Answer 1

Explanation:

A hydraulic machines works on the principle of Pascal's law

which states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid. Within the hydraulic press, there is a piston that works as a pump, that provides a modest mechanical force to a small area of the sample.

Answer 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. ... The hydraulic systems consists a number of parts for its proper functioning.The schematic of a simple hydraulic system is shown..
