  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. 
  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 
  {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
