Elasticity has meanings in two different fields:


In physics and mechanical engineering, the theory of elasticity describes how a solid object moves and deforms in response to external stress. An alternative meaning of elasticity is a property of an object: it undergoes elastic (as opposed to plastic) deformation in response to stress.


In economics, elasticity is the proportional change in one variable relative to the proportion change in another variable. The concept of elasticity can be used whenever there is a cause and effect relationship. The causal variable is often called the independent variable, while the effected variable is called the dependent variable.

Note: in economics, an inelastic relationship implies that the relationship is still proportional, but with a low constant of proportionality (e.g., price inelasticity). However, in physics, inelastic material (or inelastic collisions) do not obey the theory of elasticity: there is no constant of proportionality. In physics, a material with a high elastic modulus is still technically called elastic.

Elastic Residence (660 words)
Elastic residence is a gallery space for projects and durational performance.
Elastic Residence is an independent, artist-run project space that provides exhibition opportunities and support for artists outside the confines of a commercial or institutional framework.
Elastic does not receive any core funding for it’s exhibition programme, therefore, the cost of making and presenting the work must be met by the artist/curator, as do some of the exhibition expenses.
Elastic - definition of Elastic in Encyclopedia (408 words)
The elasticity of a solid is inversely proportional to the strength of the material.
The word elastic is often used colloquially to refer to an elastomeric material such as rubber or cloth/rubber combinations.
In that case, when a large flexibility is needed for a large surface, a folding wall is an alternative connections between railroad cars and in articulated buses, and in an accordion.
