M.E. stat, partly from M.Fr. estat, partly from L. status "manner of standing, position, condition," noun of action from p.p. stem of stare "to stand;" cognate with Pers. istâdan "to stand," as below.

2) Pertaining to → statistics.

From Mod.L. statica, from Gk. statikos "causing to stand," from stem of histanai "to cause to stand," cognate with Pers. istâdan "to stand," as below.

Istâ "standing, static," from istâdan "to stand" (Mid.Pers. êstâtan; O.Pers./Av. sta- "to stand, stand still; set;" Av. hištaiti; cf.

static equilibrium
  ترازمندی ِ ایستا   
tarâzmandi-ye istâ

Fr.: équilibre statique   

The state of a rigid body which is not moving at all. The conditions for static equilibrium are: 1) the sum of the external forces on the object must equal zero, and 2) the sum of the → torques must equal zero. → dynamic equilibrium

static; → equilibrium.

static limit

Fr.: limite stationnaire   

Same as → stationary limit.

static; → limit.

static pressure
  فشار ِ ایستا   
fešâr-e istâ

Fr.: pression statique   

In → fluid mechanics, the → pressure felt by an object suspended in a → fluid and moving with it. This pressure is called static because the object is not moving relative to the fluid. See also → dynamic pressure.

stationary black hole
  سیه‌چال ِ ایست‌ور

stationary limit surface
  رویه‌ی ِ حدّ ِ ایست‌ور   
ruye-ye hadd-e istvar

Fr.: surface limite stationnaire   

A property of → space-time outside a → rotating black hole, which consists of a surface which geometrically bounds the → ergosphere outward.
