The ratio of change in configuration produced in the body to the original configuration is called strain.
Strain is of three types;
Longitudinal Strain change in length per unit original length
Volume Strain change in volume per unit original volume
Shearing Strain when there is change of shape of a body without change in its volume, the strain produced is called shearing strain and is defined as the angle through which a plane perpendicular to the fixed surface of the cubical body gets turned under the effect of tangential force.
