Question

If longitudinal strain for a wire is $0.03$ and its poisson ratio is $0.5$, then its lateral strain is

• A. $0.003$
• B. $0.0075$
• C. $0.015$
• D. $0.4$

Answer 1

Answer: (C)

$0.015$

Poisson's ratio is defined as the ratio of lateral strain to the longitudinal strain.

$\nu =\frac{\text{Lateral Strain}}{\text{Longitudinal Strain}}$

$\text{Lateral Strain}=0.015$
