# Elasticity

Elasticity may refer to:

• Elasticity (physics), continuum mechanics of bodies that deform reversibly under stress

Numerous uses are derived from this physical sense of the term, which is inherently mathematical, such as used in Engineering, Chemistry, Construction and variously in Economics:

• Elasticity (data store), the flexibility of the data model and the clustering
• Elasticity (economics), a general term for a ratio of change. For more specific economic forms of elasticity, see:
• Beta coefficient
• Cross elasticity of demand
• Elasticity of substitution
• Frisch elasticity of labor supply
• Income elasticity of demand
• Output elasticity
• Price elasticity of demand
• Price elasticity of supply
• Yield elasticity of bond value
• Elasticity of a function, a mathematical definition of point elasticity
• Arc elasticity
• Elasticity coefficient, a biochemical term used in metabolic control analysis

### Famous quotes containing the word elasticity:

One of the reforms to be carried out during the incoming administration is a change in our monetary and banking laws, so as to secure greater elasticity in the forms of currency available for trade and to prevent the limitations of law from operating to increase the embarrassment of a financial panic.
William Howard Taft (1857–1930)

A submissive spirit might be patient, a strong understanding would supply resolution, but here was something more; here was that elasticity of mind, that disposition to be comforted, that power of turning readily from evil to good, and of finding employment which carried her out of herself, which was from Nature alone. It was the choicest gift of heaven.
Jane Austen (1775–1817)
