Question
A copper wire of length 1m is stretched by 1cm then the strain in the wire is
Solution
Strain is defined as the change in length divided by the original length.
In this case, the original length of the copper wire is 1m or 100cm. The change in length (the amount it was stretched) is 1cm.
So, to calculate the strain, you would divide the change in length (1cm) by the original length (100cm).
Strain = Change in length / Original length Strain = 1cm / 100cm = 0.01
So, the strain in the wire is 0.01.
