A rubber band is stretched to twice it's original length .calculate the strain on the rubber band
To calculate the strain on a rubber band, you need to know the original length (L0) and the final length (L).
The strain (ε) is a measure of how much an object changes in length compared to its original length. It can be calculated using the formula:
ε = (L - L0) / L0
In this case, the rubber band is stretched to twice its original length (L0). This means the final length (L) is two times the original length. So, L = 2L0.
Now, we can calculate the strain:
ε = (2L0 - L0) / L0
= L0 / L0
= 1
Therefore, the strain on the rubber band when it is stretched to twice its original length is 1.
