Question

if the iron wire is stretched by 1% then the strain on wire would be.....???​

Answer 1

Answer:

Strain is 0.01

Explanation:

Strain is defined as ratio of  change in length to original length

Let the original length  is L

So here change in length is 1% = (1/100)×L

by  strain  formula

$\epsilon=\frac{\Delta L}{L} \\\epsilon=\frac{\frac{1\times L}{100} }{L} \\\epsilon=0.01$

Hence strain is 0.01
