alleryA crane rope must not stretch beyond its:
AFracture point
BOwn length
CMelting point
DElastic limit
Answer & Solution
Correct answer: D. Elastic limit
1. The rope must not be deformed permanently.
2. Permanent set begins at the elastic limit.
3. So the extension stays below the elastic limit.
