blank range or at low angles of elevation. -- Horizontal force (Physics), the horizontal component of the earth's magnetic force. -- Horizontal line (Descriptive Geometry & Drawing), a constructive line, either drawn or imagined, which passes through the point of sight, and is the chief line in the projection upon wh…

rincipal causes of firmness are. the grossness, the quiet contact, and the implication of component parts. Boyle.

chine takes in electrical energy and acts as an induction motor; at synchronism the power component of current becomes zero and changes sign, so that above synchronism the machine (driven for this purpose by mechanical power) gives out electrical energy as a generator.

The quality or state of being an ingredient or component part. Boyle.

That which enters into a compound, or is a component part of any combination or mixture; an element; a constituent. By way of analysis we may proceed from compounds to ingredients. Sir I. Newton. Water is the chief ingredient in all the animal fluids and solids. Arbuthnot.

Incapable of being resolved; not separable into component parts. Irresolvable nebulæ (Astron.), nebulæ of a cloudlike appearance, which have not yet been resolved by the telescope into stars. Sir W. Herschel.

Being in such a state that the component parts move among themselves, but do not tend to separate from each other as the particles of gases and vapors do; neither solid nor aëriform; as, liquid mercury, in distinction from mercury solidified or in a state of vapor.

S. cynosuroides is not good for hay unless cut very young. The low S. juncea is a common component of salt hay. -- Marsh harrier (Zoöl.), a European hawk or harrier (Circus æruginosus); -- called also marsh hawk, moor hawk, moor buzzard, puttock. -- Marsh hawk. (Zoöl.) (a) A hawk or harrier (Circus cyaneus), native…

e fish of the Herring familt (Brevoortia tyrannus), chiefly valuable for its oil and as a component of fertilizers; -- called also mossbunker, bony fish, chebog, pogy, hardhead, whitefish, etc.

One of the component segments of the body of an animal.

3, not existing alone but regarded as an essential residue of methane, and appearing as a component part of many derivatives; as, methyl alcohol, methyl ether, methyl amine, etc. [Formerly written also methule, methyle, etc.] Methyl alcohol (Chem.), a light, volatile, inflammable liquid, CH3.OH, obtained by the distill…

arbon radical, CH2, not known in the free state, but regarded as an essential residue and component of certain derivatives of methane; as, methylene bromide, CH2Br2; -- formerly called also methene. Methylene blue (Chem.), an artificial dyestuff consisting of a complex sulphur derivative of diphenyl amine; -- called al…

urn to dust by natural decay; to lose form, or waste away, by a gradual separation of the component particles, without the presence of water; to crumble away. The moldering of earth in frosts and sun. Bacon. When statues molder, and when arches fall. Prior. If he had sat still, the enemy's army would have moldered to n…

nt to the line of direction of the force. (b) With respect to a line, the product of that component of the force which is perpendicular to the plane passing through the line and the point of application of the force, into the shortest distance between the line and this point. (c) With respect to a plane that is paralle…

t sense, a process or series of processes by which the living organism as a whole (or its component parts or organs) is maintained in its normal condition of life and growth.

The disposition of a column and its component parts, and of the entablature resting upon it, in classical architecture; hence (as the column and entablature are the characteristic features of classical architecture) a style or manner of architectural designing.

A component part performing an essential office in the working of any complex machine; as, the cylinder, valves, crank, etc., are organs of the steam engine.

gree of variableness (number of degrees of freedom) of a system is equal to the number of components minus the number of phases, plus two. Thus, if the components be salt and water, and the phases salt, ice, saturated solution, and vapor, the system is invariant, that is, there is only one set of conditions under which…

such that its differential coefficients with respect to the coördinates are equal to the components of the force at the point considered; -- also called potential function, or force function. It is called also Newtonian potential when the force is directed to a fixed center and is inversely as the square of the distan…
