Such an alloy can be cast like ordinary bronze, but excels the latter in hardness, elasticity, toughness and tensile strength.

Most metals when molten are capable of dissolving at least small proportions of carbon, which, in general, leads to a deterioration in metallicity, except in the case of iron, which by the addition of small percentages of carbon gains in elasticity and tensile strength with little loss of plasticity.

The isothermal elasticity - v(dp/dv) is equal to the pressure p. The adiabatic elasticity is equal to y p, where -y is the ratio S/s of the specific heats.

Let E be the bulk modulus of elasticity, defined as increase of pressure = decrease of volume per unit volume where the pressure increase is so small that this ratio is constant, w the small increase of pressure, and - (dy/dx) the volume decrease, then E=e/(- dy/dx) or w Æ= - dy/dx (I) This gives the relation between pressure excess and displacement.

The keys which hold the rail in the chairs are usually of oak and are placed outside the rails; the inside position has also been employed, but has the disadvantage of detracting from the elasticity of the road since the weight of a passing train presses the rails up against a rigid mass of metal instead of against a slightly yielding block of wood.

Possibly the advantages of specialism might be retained and yet the elasticity of supply be enhanced.

For example, the physicist determines the density, elasticity, hardness, electrical and thermal conductivity, thermal expansion, &c.; the chemist, on the other hand, investigates changes in composition, such as may be effected by an electric current, by heat, or when two or more substances are mixed.

When caoutchouc is heated slightly above the temperature of boiling water it becomes softer and loses much of its elasticity, which, however, it recoveres on cooling.

This condition manifests itself, for example, in mine pillars which are subjected to a weight beyond the limit of elasticity of the mineral of which they are composed.

But their most characteristic, though not perhaps their most general, property is that they combine in themselves the apparently incompatible properties of elasticity and rigidity on the one hand and plasticity on the other.

Strains exceeding the "limit of elasticity" result in permanent deformation or (if sufficiently great) in rupture.

Changes of elasticity are in all cases dependent, not only upon the field, but also upon the tension applied; and, owing to hysteresis, the results are not in general the same when the magnetization follows as when it precedes the application of stress; the latter is held to be the right order.

If we write K for the adiabatic elasticity, and k for the isothermal elasticity, we obtain S/s = ECÆF = K/k.

The energy of this fork with a given amplitude of vibration could be calculated from its dimensions and elasticity, and the amplitude was observed by measuring with a microscope the line into which the image of a starch grain on the prong was drawn by the vibration.

These are for the most part interesting rather from the point of view of elasticity than of sound.

Its physical properties, permeability by water, extensibility and elasticity, receive their interpretation in the needs of the latter.

An experiment by Ewing showed that by the operation of stretching an annealed iron wire beyond the limits of elasticity the permeability under a magnetizing force of about 3 units was reduced by as much as 75%.

An unfinished work, The History of the Theory of Elasticity, was edited and published posthumously in 1886 by Karl Pearson.

If the rod is circular in section and perfectly uniform the end will describe a circle, ellipse or straight line; but, as the elasticity is usually not exactly the same in all directions, the figure usually changes and revolves.

Owing to the yielding of joints when a beam is first loaded a smaller modulus of elasticity should be taken than for a solid bar.

Light is therefore an influence propagated as wave-motion, and moreover by transverse undulations, for the reasons brought out by Thomas Young and Augustin Fresnel; so that the aether is a medium which possesses elasticity of a type analogous to rigidity.

The Latin Church, which, by combining the tradition of the Roman centralized organization with a great elasticity in practice and in the interpretation of doctrine, had hitherto been the moulding force of civilization in the West, is henceforth more or less in antagonism to that civilization, which advances in all its branches - in science, in literature, in art - to a greater or less degree outside of and in spite of her, until in its ultimate and most characteristic developments it falls under the formal condemnation of the pope, formulated in the famous Syllabus of 1864.

A medusa has a layer of muscles, more or less strongly developed, running in a circular direction on the surface of the subumbrella, the contractions of which are antagonized by the elasticity of the gelatinous substance of the body.

Short fibre silks are still put through cards and treated like cotton; but the value of silk is in its lustre, elasticity and strength, which characteristics are obtained by keeping fibres as long as possible.

It is easily seen from (6) that if the configuration of a system of particles be altered by homogeneous strain (see ELASTICITY) the new position of the mass-centre will be at that point of the strained figure which corresponds to the original mass-centre.

On being relieved from picket duty Rostov had managed to get a few hours' sleep before morning and felt cheerful, bold, and resolute, with elasticity of movement, faith in his good fortune, and generally in that state of mind which makes everything seem possible, pleasant, and easy.

Lastly, the lower back area is not usually affected by changes of body weight, skin elasticity, etc., making it an ideal area for a tattoo inked with the intention of being long-lasting and fade proof.

This antioxidant also improves the skin's firmness and elasticity.

As we age, skin loses its natural elasticity which helps to keep the skin and the pores tight.

As you age, skin loses elasticity and vital natural chemicals.

Pores enlarge when skin loses overall elasticity.

The quadrate muscle adjusts the motion, and prevents pressure upon the optic nerve; during the state of relaxation of both muscles the nictitans withdraws through its own elasticity.

Pure lead isa feebly lustrous bluishwhite metal, endowed with a characteristically high degree of softness and plasticity, and almost entirely devoid of elasticity.

In the fibrils existing in the cell a sudden alteration of elasticity occurs, resulting in an increased tension on the points of attachment of the cell to the neighbouring elements of the tissue in which the cell is placed.

Metallic thallium is bluish white; it is extremely soft and almost devoid of tenacity and elasticity.

A difference in calibre, elasticity or branching of a blood vessel, the smallest variation in a nerve or group of vessel-cells, any anatomical or physiological divergence, is reflected throughout the organism.

The wood is very tough and strong, and superior to most wood in elasticity; and it weighs 40 to 55 lb per cub.

In the form of plate it can be tempered and annealed till its elasticity and toughness are much increased, and it can then be formed into almost any shape under the hammer and punch.

One of the most difficult problems with which the metal-worker who handles constructional forms has to deal is the maintenance of a due relation between absolute strength and a useful degree of elasticity.

Only after many failures has the fact been grasped that a very high degree of strength is inconsistent with a trustworthy degree of elasticity.

His style is perfectly perspicuous, and its "strong home-touch" compensates for what is lacking in elasticity and grace.

Statics of Inextensible Chains.The theory of bodies or structures which are deformable in their smallest parts belongs properly to elasticity.

This appears to be the case very approximately with steel or glass balls; generally, however, there is some appreciable loss of apparent energy; this is accounted for by vibrations produced in the balls and imperfect elasticity of the materials.

The effect of the pressures applied to a piece, consisting of the load and the sispporting resistances, is to force the piece into a state of strain or disfigurement, which increases until the elasticity, or resistance to strain, of the material causes it to exert a stress, or effort to recover its figure, equal and opposite to the system of applied pressures.
