Elastic fluid
(gcide) | Fluid \Flu"id\, n.
A fluid substance; a body whose particles move easily among
themselves.
[1913 Webster]
Note: Fluid is a generic term, including liquids and gases as
species. Water, air, and steam are fluids. By analogy,
the term was sometimes applied to electricity and
magnetism, as in phrases electric fluid, magnetic
fluid, though not strictly appropriate; such usage has
disappeared.
[1913 Webster +PJC]
Fluid dram, or Fluid drachm, a measure of capacity equal
to one eighth of a fluid ounce.
Fluid ounce.
(a) In the United States, a measure of capacity, in
apothecaries' or wine measure, equal to one sixteenth of
a pint or 29.57 cubic centimeters. This, for water, is
about 1.04158 ounces avoirdupois, or 455.6 grains.
(b) In England, a measure of capacity equal to the twentieth
part of an imperial pint. For water, this is the weight
of the avoirdupois ounce, or 437.5 grains.
Fluids of the body. (Physiol.) The circulating blood and
lymph, the chyle, the gastric, pancreatic, and intestinal
juices, the saliva, bile, urine, aqueous humor, and muscle
serum are the more important fluids of the body. The
tissues themselves contain a large amount of combined
water, so much, that an entire human body dried in vacuo
with a very moderate degree of heat gives about 66 per
cent of water.
Burning fluid, Elastic fluid, Electric fluid, {Magnetic
fluid}, etc. See under Burning, Elastic, etc.

and E. alacrity: cf. F. ['e]lastique.]
1. Springing back; having a power or inherent property of
returning to the form from which a substance is bent,
drawn, pressed, or twisted; springy; having the power of
rebounding; as, a bow is elastic; the air is elastic;
India rubber is elastic.
[1913 Webster]
Capable of being drawn out by force like a piece of
elastic gum, and by its own elasticity returning,
when the force is removed, to its former position.
--Paley.

2. Able to return quickly to a former state or condition,
after being depressed or overtaxed; having power to

(b) (Mech.) The figure assumed by the longitudinal axis of
an originally straight bar under any system of bending
forces. --Rankine.
Elastic fluids, those which have the property of expanding
in all directions on the removal of external pressure, as
the air, steam, and other gases and vapors.
Elastic limit (Mech.), the limit of distortion, by bending,
stretching, etc., that a body can undergo and yet return
to its original form when relieved from stress; also, the
unit force or stress required to produce this distortion.
Within the elastic limit the distortion is directly
proportional to the stress producing it.
Elastic tissue (Anat.), a variety of connective tissue
consisting of a network of slender and very elastic fibers
which are but slightly affected by acids or alkalies.
