Hydraulics
The science and engineering of fluid mechanics under pressure, particularly the flow, control, and application of liquids in various systems.
Hydraulics
Hydraulics is the branch of science and engineering that deals with the mechanical properties of fluids, particularly liquids, and their applications in mechanical systems. This field forms a cornerstone of modern engineering and has applications ranging from industrial machinery to everyday devices.
Fundamental Principles
The core principles of hydraulics are based on Pascal's Law, which states that pressure applied to a confined fluid is transmitted equally in all directions. This fundamental concept enables:
- Force multiplication through pressure differences
- Power transmission through fluid movement
- Energy conversion between mechanical and hydraulic forms
