Answer:
In mechanics, Poisson's ratio is the negative of the ratio of transverse strain to lateral or axial strain. It is named after Siméon Poisson and denoted by the Greek letter 'nu', It is the ratio of the amount of transversal expansion to the amount of axial compression for small values of these changes.
