Question

The Poisson’s ratio for a metal is 0.25. If lateral strain is 0.0125, the longitudinal strain will be

• A. 0.125
• B. 0.05
• C. 0.215
• D. 0.0125

Answer 1

Answer: (B)

0.05

Answer 2

$\therefore$Longitudinal strain $= \frac { \text { Lateral strain } } { \sigma }$ $= \frac { 0.0125 } { 0.25 }$ $= 0.05$
