  Hydrostatic \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.
     [1913 Webster]


  
           The first discovery made in hydrostatics since the time
           of Archimedes is due to Stevinus.        --Hallam.
     [1913 Webster]
  
     {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.
