Question

Poisson's ratio in the ratio of the lateral strain to....​

Answer 1

Poisson's ratio is defined as the ratio of the lateral strain to the longitudinal strain with the (-)ve sign.

Explanation:-

• When a force is applied on the material and due to that force some deformation occurs in the longitudinal direction and some in the lateral direction. Then, ratio of lateral to the longitudinal strain is known as Poisson's ratio. It is represented by the symbol $\mu$

                                              $\Rightarrow \mu=-\dfrac{\epsilon_{y}}{\epsilon_{x}}$

• (-)ve sign is used because increase in longitudinal deformation always results in decrease in lateral deformation.
• Practically, $0\leq \mu\geq 0.5$
