PASCAL'S LAW
“pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same.”
APPLICATIONS
Hydraulics used in many applications:
Steering/control systems (rudder, planes)
Deck machinery (anchor windlass, capstans, winches)
Masts & antennae on submarines
Weapons systems (loading & launching)
Other: elevators, presses
ADVANTAGES
Convenient power transfer
Few moving parts
Low losses over long distances
Little wear
Flexibility
Distribute force in multiple directions
Safe and reliable for many uses
Can be stored under pressure for long periods
Variable speed control
Quick response (linear and rotary)
