1. The problem statement, all variables and given/known data 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. 2. Relevant equations E=stress/strain 3. The attempt at a solution My working is together with the question.
