== Explanation ==
Strain expresses the magnitude of deformation caused due to the [[stress]] in a system due to the applied load or [[force]]. It is denoted by '''e'''. The strain of a rod subjected to a stress is simply the ratio of the deformed length '''l''' to it original length '''L'''. Strain, '''e = l/L''', is a dimensionless number that is usually expressed in percentages.
