Longitudinal strain $= \frac{change in length}{original length}$
If 1 be the original length and if stretched to double of its length, change in length $= 1$
So, strain $= 1$

Longitudinal strain = original length change in length ​ If 1 be the original length and if stretched to double of its length, change in length =1 So, strain =1

Longitudinal strain $= \frac{change in length}{original length}$
If 1 be the original length and if stretched to double of its length, change in length $= 1$
So, strain $= 1$
