Question

The poissons ratio is a ratio
of two​

Answer 1

Answer:

Poisson's ratio is the ratio of transverse contraction strain to longitudinal extension strain in the direction of stretching force. Tensile deformation is considered positive and compressive deformation is considered negative.

Answer 2

Answer:

its the ratio of Lateral strain to Longitudinal strain

d = diameter of the wire

Δd = change in diameter

L = length of wire

ΔL = change in length

the Poisson's ratio is

(Δd/d)/(ΔL/L)

or

(ΔD/ΔL)  × (L/D)
