EasyIf under an external force,a change in length $\Delta l$ occurs in a rod of original length $l$,then write the formula for longitudinal strain.
(N/A) Longitudinal strain is defined as the ratio of the change in length to the original length of the object.
Formula: $\varepsilon_{l} = \frac{\Delta l}{l}$
Formula: $\varepsilon_{l} = \frac{\Delta l}{l}$
