What is actually poisson's ratio.. Read it u will learn something most important

Poisson's ratio is defined as the negative of the ratio of the lateral strain to the axial strain for a uniaxial stress state. If a tensile load is applied to a material, the material will elongate on the axis of the load ﴾perpendicular to the tensile stress plane﴿, Tensile deformation is considered...

==>> THEORY OF STRAIN==>>

STRAIN==>> When a body is subjected to some external force, there is some change of dimension of the body. The ratio of the change in dimension of the body to the original dimension is known as strain.. =>Strain is dimension less quantity... generally STRAIN = change in length / original length  TYPES OF STRAIN==>> => TENSILE STRAIN  => COMPRESSIVE STRAIN =>VOLUMETRIC...
