alleryYou stretch a wire and its diameter shrinks slightly. The strain across the wire is called:
AThermal strain
BLateral strain
CVolume strain
DShear strain
Answer & Solution
Correct answer: B. Lateral strain
1. The wire gets thinner as it gets longer.
2. This strain is perpendicular to the pull.
3. It is the lateral strain.
