Question

Explain the principle of the hydraulic machine?

Answer 1

1. Hydraulic press works on the principle of Pascal's law.
2. It states that a pressure change occurring anywhere in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.
3. It states that a small force applied on a smaller piston is transmitted to produce a large force on the bigger piston.
4. Hydraulic brakes and hydraulic press work on this principle.
