The basic concept of hydraulics is using the force of a liquid to take up a volume and to push on a movable cylinder. Hydraulics use the physics described by "Pascal's Law" which states that pressure applied at any point upon a confined liquid is transmitted undiminished in all directions. Thus the cylinder will supply the least amount of opposing force the the pressurized liquid and thus is moved by the pressurized liquid (usually oil). This movable cylinder is usually connected to the part of the machine that you want to move. The benefit of hydraulics is that you are able to supply large amounts of force through movable pipes and hoses using an incompressible liquid.
By definition, power is equal to the rate at which energy is transferred in units of Joule/second. In the case of hydraulics, power is most easily understood by looking at the equation:
P = F*v where P is power, F is force and v is velocity
Force is found by multiplying the pressure that is placed on the cylinder by the ...
