Pascals
The basic principle of a hydraulic press is that the hydraulic oil pressure remains constant in an enclosed system, where, the area on which it acts, will generate a force equal to the area multiplied by the pressure (where, pressure is equal to force per unit area). This is well defined as per pascal's law, for which, pl refer wikiepedia.
A hydraulic system.
In mobile hydraulics, those used in agricultural, industrial, and automotive applications a hydraulic accumulator works like a shock absorber for a hydraulic system. Often a hydraulic accumulator is composed of a housing with a diaphragm between the oil side and the gas side. Pressurized gas (usually dry nitrogen because of its low expansion/contraction properties in relationship to temperature). The accumulator will have a specification for the gas pressure and the hydraulic system can often be used to manipulate the pressure of the oil used in the accumulator depending upon a specific application. Rapid increases and decreases for hydraulic power demands (most often occurring in open-center systems) can shock the hydraulic pump, lines and valves. Open-center positive-displacement systems (constantly providing hydraulic flow while the engine is running) must return to sump when there is no hydraulic need. This is done by use of a relief valve or a 'dump'-valve on the pressure side of the system. There are moments when the relief valve may have a very slight delay. This delay can cause the system to build pressure in a very short period of time and this can strain hydraulic components. So the accumulator it used to soften the blow just a little. Another example would be when using a float application with a hydraulic system, an accumulator may help to buffer the changing oil directions within the hydraulic system.

Air trapped in a hydraulic system will decrease efficiency and increase wear on the system. Motors will run at a decreased efficiency and cylinders will seem spongy feeling and not produce the same pushing forces. Pump wear will increase, and cavitation will occur.

Bernoulli's principle. The above answer is wrong. Its Pascal's Principle :)

Pascal's principle is the foundation of modern hydraulics

The principles of operation of the automatic voltage regulator is that of the excitation system. The working principle is to regulate the flow of reinforcement on the exciter.
It is telemetry system with hydraulic
because light aircraft use the basic hydraulic system for its operation so its not necassary to be there
A hydraulic drive system is a transmission system. This system uses hydraulic fluid that has been pressurized to make a machine work. Most of these systems utilize hydraulic cylinders.
Hydraulic system make use of hydraulic devices to perform a variety of functions.
Federalism is the principle that gives power to the state governments. The U.S. Constitution divides the powers between the states and the Federal government.
