The ability of a solid to recover its original form when a stress is applied and quickly removed The elastic limit is the greatest stress that a material is capable of sustaining without permanent deformation remaining on the complete release of the stress The modulus of elasticity is the ratio of stress to strain in a material that is elastically deformed The yield value is the lowest stress at which a material undergoes plastic deformation Below this stress, the material is elastic, above it, viscous
The condition when the percentage change in quantity demanded is greater than the percentage change in price
The elasticity of a material or substance is its ability to return to its original shape, size, and condition after it has been stretched. Daily facial exercises help her to retain the skin's elasticity. Ability of a deformed material body to return to its original shape and size when the forces causing deformation are removed. Most solids show some elastic behaviour, but there is usually a limit the material's "elastic limit" to the force from which recovery is possible. Stresses beyond its elastic limit cause the material to yield, or flow, and the result is permanent deformation or breakage. The limit depends on the material's internal structure; for example, steel, though strong, has a low elastic limit and can be extended only about 1% of its length, whereas rubber can be elastically extended up to about 1,000%. Robert Hooke, one of the first to study elasticity, developed a mathematical relation between tension and extension
The property of an article which tends to return to its original shape after deformation Elongation - Extension produced by a tensile stress Expanded Rubber - Cellular rubber having closed cells made from a solid rubber compound Extrusion - 1) Distortion, under pressure, of portion of seal into clearance between mating metal parts 2) Material, under pressure, which is forced through the opening of a die in order to obtain a desired cross sectional shape
Refers to the sensitivity of the quantity supplied or demanded of a commodity as the price of that commodity changes A commodity demand or supply that is elastic will change in response to price movements while an inelastic demand or supply is relatively unresponsive to changes in price
The property of an article which tends to return it to its original shape after deformation
The property of an article, which tends to return to its original shape after deformation
The ability of a fiber or fabric to return to its original length, shape, or size immediately after the removal of stress
