\Hy`dro*stat"ic\, Hydrostatical \Hy`dro*stat"ic*al\,
a. [Hydro-, 1 + Gr. ? causing to stand: cf. F. hydrostatique.
See {Static}.]
Of or relating to hydrostatics; pertaining to, or in
accordance with, the principles of the equilibrium of fluids.
      The first discovery made in hydrostatics since the time
      of Archimedes is due to Stevinus.        --Hallam.
{Hydrostatic balance}, a balance for weighing substances in
   water, for the purpose of ascertaining their specific
   gravities.
{Hydrostatic bed}, a water bed.
{Hydrostatic bellows}, an apparatus consisting of a
   water-tight bellowslike case with a long, upright tube,
   into which water may be poured to illustrate the
   hydrostatic paradox.
{Hydrostatic paradox}, the proposition in hydrostatics that
   any quantity of water, however small, may be made to
   counterbalance any weight, however great; or the law of
   the equality of pressure of fluids in all directions.
{Hydrostatic press}, a machine in which great force, with
   slow motion, is communicated to a large plunger by means
   of water forced into the cylinder in which it moves, by a
   forcing pump of small diameter, to which the power is
   applied, the principle involved being the same as in the
   hydrostatic bellows. Also called {hydraulic press}, and
   {Bramah press}. In the illustration, a is a pump with a
   small plunger b, which forces the water into the cylinder
   c, thus driving upward the large plunder d, which performs
   the reduced work, such as compressing cotton bales, etc.
