Answer:
The Poisson's ratio (ν) is a method to relate the longitudinal deformation of a material with its simultaneous lateral deformation.
Explanation:
The Poisson's ratio (ν) is a method to relate the longitudinal deformation of a material with its simultaneous lateral deformation.
It can be expressed as
It is a measure of the Poisson effect, in which a material tend to expand in directions perpendicular to the direction of compression.
