Question: If a wire is stretched and its length increases by 2%, what is the strain?
Options:
0.02
0.2
2
200
Correct Answer: 0.02
Solution:
Strain is defined as the change in length divided by the original length, so 2% = 0.02.

Questions & Step-by-Step Solutions
If a wire is stretched and its length increases by 2%, what is the strain?
Step 1: Understand that strain is a measure of how much a material deforms compared to its original size.
Step 2: Know that strain is calculated using the formula: Strain = (Change in Length) / (Original Length).
Step 3: In this question, the wire's length increases by 2%.
Step 4: Convert the percentage increase into a decimal for calculation: 2% = 2/100 = 0.02.
Step 5: Since the change in length is 0.02 times the original length, we can say that the strain is 0.02.
Strain – Strain is a measure of deformation representing the displacement between particles in a material body, calculated as the change in length divided by the original length.
