alleryStart learning →Poisson's ratio for steel is approximately:
A~0.3
B~0.5
C~1
D0
Answer & Solution
Correct answer: A. ~0.3
Poisson's ratio (ν): ratio of lateral strain to longitudinal strain (with sign change).
**Steel:** ~0.3. Concrete: ~0.15-0.20. Rubber: ~0.5 (incompressible).
**Cork:** ~0 (no lateral change).
**Theoretical limit:** -1 to 0.5. Auxetic materials have negative ν.
