Elastic Moduli ComparisonHardQuestion 6336

Question

Poisson's ratio ν = −(lateral strain)/(longitudinal strain). For steel ν ≈ 0.3. If wire stretches by 0.1%, lateral strain:
  1. A
    0.03%
    Correct
  2. B
    0.1%
  3. C
    0.003%
  4. D
    0.3%

Correct answer

0.03%

Explanation

Lateral strain = ν × longitudinal strain = 0.3 × 0.1% = 0.03%.
