Discounting principle. - Discounting principle: Discounting principle refers to a rule of Attribution which states that the perceived role of a cause will be discounted or reduced if other plausible causes are also present.
The Poisson Effect When a tensile stress is applied to a material, the material elongates in the direction of the applied stress, and contracts perpendicular to the direction of the applied stress. This relationship, called the Poisson effect, is a natural response to applied stress that occurs with all materials, but is particularly apparent with ductile materials. For example, when a metal bar is pulled in a tensile test, it stretches out and necks down on. the sides.
Poisson's ratio, named after Simeon SimÃ©on, poisson also known as the coefficient of expansion on the transverse, axial is the negative ratio of transverse to axial. Strain when a material is compressed in one, direction it usually tends to expand in the other two directions perpendicular to the direction of. compressionhis phenomenon is called the Poisson effect. Poisson's ratio (nu) is a measure of this effect. The Poisson ratio is the fraction (or percent) of expansion divided by the fraction (or percent) of compression, for small values of these changes.
