Question

What is Poisson's ratio?

Options

• \[\frac {\text{linear strain}}{\text{lateral strain}}\]

• \[\frac {\text{lateral strain}}{\text{linear strain}}\]

• \[\frac {\text{stress}}{\text{strain}}\]

• \[\frac {\text{volume}}{\text{pressure}}\]

Answer 1

\[\frac {\text{lateral strain}}{\text{linear strain}}\]

Explanation:

Poisson's ratio is defined as the ratio of lateral strain (change perpendicular to applied force) to linear strain (change in the direction of applied force).
