[1913 Webster]Engineering \En`gi*neer"ing\, n.
Originally, the art of managing engines; in its modern and
extended sense, the art and science by which the properties
of matter are made useful to man, whether in structures,
machines, chemical substances, or living organisms; the
occupation and work of an engineer. In the modern sense, the
application of mathematics or systematic knowledge beyond the
routine skills of practise, for the design of any complex
system which performs useful functions, may be considered as
engineering, including such abstract tasks as designing
software (software engineering).
[1913 Webster +PJC]
Note: In a comprehensive sense, engineering includes
architecture as a mechanical art, in distinction from
architecture as a fine art. It was formerly divided
into military engineering, which is the art of
designing and constructing offensive and defensive
works, and civil engineering, in a broad sense, as
relating to other kinds of public works, machinery,
etc.
Civil engineering, in modern usage, is strictly the art of
planning, laying out, and constructing fixed public works,
such as railroads, highways, canals, aqueducts, water
works, bridges, lighthouses, docks, embankments,
breakwaters, dams, tunnels, etc.
Mechanical engineering relates to machinery, such as steam
engines, machine tools, mill work, etc.
Mining engineering deals with the excavation and working of
mines, and the extraction of metals from their ores, etc.
Engineering is further divided into steam engineering, gas
engineering, agricultural engineering, topographical
engineering, electrical engineering, etc.
[1913 Webster] |
Mechanical equivalent of heat
(gcide) | Equivalent \E*quiv"a*lent\ ([-e]*kw[i^]v"[.a]*lent), n.
1. Something equivalent; that which is equal in value, worth,
weight, or force; as, to offer an equivalent for damage
done.
[1913 Webster]
He owned that, if the Test Act were repealed, the
Protestants were entitled to some equivalent. . . .
During some weeks the word equivalent, then lately
imported from France, was in the mouths of all the
coffeehouse orators. --Macaulay.
[1913 Webster]
2. (Chem.) That comparative quantity by weight of an element
which possesses the same chemical value as other elements,
as determined by actual experiment and reference to the
same standard. Specifically:
(a) The comparative proportions by which one element
replaces another in any particular compound; thus, as
zinc replaces hydrogen in hydrochloric acid, their
equivalents are 32.5 and 1.
(b) The combining proportion by weight of a substance, or
the number expressing this proportion, in any
particular compound; as, the equivalents of hydrogen
and oxygen in water are respectively 1 and 8, and in
hydric dioxide 1 and 16.
[1913 Webster]
Note: This term was adopted by Wollaston to avoid using the
conjectural expression atomic weight, with which,
however, for a time it was practically synonymous. The
attempt to limit the term to the meaning of a
universally comparative combining weight failed,
because of the possibility of several compounds of the
substances by reason of the variation in combining
power which most elements exhibit. The equivalent was
really identical with, or a multiple of submultiple of,
the atomic weight.
[1913 Webster]
3. (Chem.) A combining unit, whether an atom, a radical, or a
molecule; as, in acid salt two or more equivalents of acid
unite with one or more equivalents of base.
[1913 Webster]
Mechanical equivalent of heat (Physics), originally defined
as the number of units of work which the unit of heat can
perform, equivalent to the mechanical energy which must be
expended to raise the temperature of a pound of water one
degree Fahrenheit; later this value was defined as one
British thermal unit (B.t.u). Its value was found by
Joule to be 772 foot pounds; later measurements give the
value as 777.65 foot-pounds, equivalent to 107.5
kg-meters. This value was originally called Joule's
equivalent, but the modern Joule is defined differently,
being 10^7 ergs. The B.t.u. is now given as 1,054.35
absolute Joules, and therefore 1 calorie (the amount of
heat needed to raise one gram of water one degree
centigrade) is equivalent to 4.186 Joules.
[1913 Webster + PJC]
Note: The original definition of the Mechanical equivalent of
heat in the 1913 Webster was as below. The difference
between foot pounds and kilogram-meters ("on the
centigrade scale") is puzzling as it should be a factor
of 7.23, and the figure given for kilogram-meters may
be a mistaken misinterpretation of the report. -- PJC:
The number of units of work which the unit of heat can
perform; the mechanical energy which must be expended
to raise the temperature of a unit weight of water from
0[deg] C. to 1[deg] C., or from 32[deg] F. to 33[deg]
F. The term was introduced by Dr. Mayer of Heilbronn.
Its value was found by Joule to be 1390 foot pounds
upon the Centigrade, or 772 foot pounds upon the
Fahrenheit, thermometric scale, whence it is often
called Joule's equivalent, and represented by the
symbol J. This is equal to 424 kilogram meters
(Centigrade scale). A more recent determination by
Professor Rowland gives the value 426.9 kilogram
meters, for the latitude of Baltimore.
[1913 Webster +PJC]Heat \Heat\ (h[=e]t), n. [OE. hete, h[ae]te, AS. h[=ae]tu,
h[=ae]to, fr. h[=a]t hot; akin to OHG. heizi heat, Dan. hede,
Sw. hetta. See Hot.]
1. A force in nature which is recognized in various effects,
but especially in the phenomena of fusion and evaporation,
and which, as manifested in fire, the sun's rays,
mechanical action, chemical combination, etc., becomes
directly known to us through the sense of feeling. In its
nature heat is a mode of motion, being in general a form
of molecular disturbance or vibration. It was formerly
supposed to be a subtile, imponderable fluid, to which was
given the name caloric.
[1913 Webster]
Note: As affecting the human body, heat produces different
sensations, which are called by different names, as
heat or sensible heat, warmth, cold, etc., according to
its degree or amount relatively to the normal
temperature of the body.
[1913 Webster]
2. The sensation caused by the force or influence of heat
when excessive, or above that which is normal to the human
body; the bodily feeling experienced on exposure to fire,
the sun's rays, etc.; the reverse of cold.
[1913 Webster]
3. High temperature, as distinguished from low temperature,
or cold; as, the heat of summer and the cold of winter;
heat of the skin or body in fever, etc.
[1913 Webster]

[1913 Webster]
4. Indication of high temperature; appearance, condition, or

5. A single complete operation of heating, as at a forge or
in a furnace; as, to make a horseshoe in a certain number
of heats.
[1913 Webster]
6. A violent action unintermitted; a single effort; a single

remaining or becoming fluid, is diffused throughout the
solvent; also, the product resulting from such absorption.
[1913 Webster]
Note: When a solvent will not take in any more of a substance
the solution is said to be saturated. Solution is of
two kinds; viz.: (a) Mechanical solution, in which no
marked chemical change takes place, and in which, in
the case of solids, the dissolved body can be regained
by evaporation, as in the solution of salt or sugar in
water. (b) Chemical solution, in which there is
involved a decided chemical change, as when limestone
or zinc undergoes solution in hydrochloric acid.
Mechanical solution is regarded as a form of
molecular or atomic attraction, and is probably
occasioned by the formation of certain very weak and
unstable compounds which are easily dissociated and
pass into new and similar compounds.

solution of mercuric iodide in potassium iodide (called
the Sonstadt solution or Thoulet solution) having a
maximum specific gravity of 3.2, or of borotungstate of
cadium (Klein solution, specific gravity 3.6), and the
like. Such solutions are much used in determining the
specific gravities of minerals, and in separating them
when mechanically mixed as in a pulverized rock.
Nessler's solution. See Nesslerize.
Solution of continuity, the separation of connection, or of
connected substances or parts; -- applied, in surgery, to
a fracture, laceration, or the like. "As in the natural
body a wound, or solution of continuity, is worse than a
corrupt humor, so in the spiritual." --Bacon.
Standardized solution (Chem.), a solution which is used as
a reagent, and is of a known and standard strength;
specifically, a normal solution, containing in each cubic

painting, engraving, sculpture, and architecture; but the
term is often confined to painting, sculpture, and
architecture.

among the Romans, only freemen were permitted to pursue)
were, in the Middle Ages, these seven branches of
learning, -- grammar, logic, rhetoric, arithmetic,
geometry, music, and astronomy. In modern times the
