## Homework Statement

Please refer to the image attached.

I don't understand why can they just take 1.8m as the original length, since there is already a load hanging there.

My calculations yield the value of strain to be e/L, but in the answer it is e/1.8.

Please explain this to me.

## Homework Equations

E=stress/strain
