$please \: answer \: this \: question \: with \: explanation \\ \\ if \: a \: wire \: is \: stretched \: to \: double \: of \: its \: original \: length \: then \: the \: strain \: in \: the \: wire \: is$______

​

Answer 1

Answer:

Longitudinal Strain is ratio of change in length to original length. Wire is stretched to double it's original length. Hence change in length = 2×L - L (where L is original length. ) Therefore change in length is L.

longitudinal strain = change in length / original length  

if l be the original length and if stretched to double of its length , change in length = l  

so , strain = 1
