liquids are virtually incompressible and can flow
so the force applied to one point will be
transmitted equally to other points in liquid
pressure = force / area
Pressure is measured in pascals or newton metres
force is measured in newtons
area is measured in metres squared
the force exerted by a hydraulics system depends on the force that is exerted on
the system, the area of the cylinder which this force acts on and the area of the
cylinder that exerts the force
