Elastic Modulus. The Elastic or Young's modulus ( E ) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. Shear Modulus

Here we describe single crystals of a well-known coordination compound-copper(II) acetylacetonate-that are flexible enough to be reversibly tied into a knot. Mechanical measurements indicate that the crystals exhibit an elasticity similar to that of soft materials such as nylon, and thus display properties normally associated with both hard and ...

Perfectly elastic demand and perfectly inelastic demand are the two extreme limiting cases of the price elasticity of demand, and as such as rarely found in the real world. In the case of a perfectly elastic demand, the people cease to buy the commodity altogether in case of a slight rise in its price.
