1
Q
how compressible are liquids
A
liquids are virtually incompressible
2
Q
how is the pressure transmitted in a liquid (and what does this mean)
A
the pressure in a liquid is transmitted equally in all directions. this means that a force exerted at one point on a liquid will be transmitted to other points in the liquid.
3
Q
what is the relationship between pressure, force and cross sectional area
A
pressure = force / cross sectional area. P = F / A
4
Q
what enables a hydraulic system to be used as a force multiplier
A
the use of different cross-section areas on the effort and load side of a hydraulic system enables the system to be used as a force multiplier.
