The Flory theory of rubber elasticity suggests that rubber elasticity has primarily entropic origins. By using the following basic equations for Helmholtz free energy and its discussion about entropy, the force generated from the deformation of a rubber chain from its original unstretched conformation can be derived.
Elasticity is an important concept in neoclassical economic theory, and enables in the understanding of various economic concepts, such as the incidence of indirect taxation, marginal concepts relating to the theory of the firm, distribution of wealth, and different types of goods relating to the theory of consumer choice.
Professor Leslie Ronald George Treloar, OBE (30 July 1906 [1] – 18 March 1985) was a leading figure in the science of rubber and elasticity, [2] and writer of a number of influential texts. Leslie Treloar graduated in Physics from University College, Reading , in 1927 and subsequently joined GEC .
The Gent hyperelastic material model [1] is a phenomenological model of rubber elasticity that is based on the concept of limiting chain extensibility. In this model, the strain energy density function is designed such that it has a singularity when the first invariant of the left Cauchy-Green deformation tensor reaches a limiting value .
The cobweb model or cobweb theory is an economic model that explains why prices may be subjected to periodic fluctuations in certain types of markets.It describes cyclical supply and demand in a market where the amount produced must be chosen before prices are observed.
70% of the world's supply of natural rubber goes into making tires. The explosion of rubber plantations in Cambodia over the past few decades has displaced thousands of people and caused mass ...
Federal Reserve Chair Jerome Powell said he won't step down if President-elect Donald Trump, who has previously criticized Powell's performance, asks him to resign.
In economics, the Hicks–Marshall laws of derived demand assert that, other things equal, the own-wage elasticity of demand for a category of labor is high under the following conditions: When the price elasticity of demand for the product being produced is high (scale effect). So when final product demand is elastic, an increase in wages will ...
