alleryWhat units does Poisson ratio carry?
AIt has pascal units
BIt has newton units
CIt has no units
DIt has joule units
Answer & Solution
Correct answer: C. It has no units
1. Poisson ratio divides the lateral strain by the longitudinal strain.
2. Each strain is itself a pure ratio with no units.
3. So Poisson ratio is a pure number with no dimensions or units.
