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 STRAIN
=>SHEAR STRAIN
TENSILE STRAIN==>> If there is some increase in length of the body due to external force, then ratio of increase of length to the original length of the body is known as tensile strain.
COMPRESSIVE STRAIN==>> If there is some decrease in length of the body , then the ratio of decrease in length of the body to the original length is known as compressive strain.
VOLUMETRIC STRAIN==>> The ratio of change in the volume of the body to the original volume of the body is known as volumetric strain..
SHEAR STRAIN==>> The strain produce of shear stress is known as shear strain..
