Question

Poisson ratio derive necessary formula for it

Answer 1

Poisson's ratio, denoted by the Greek letter {\displaystyle \nu } \nu (nu), and named after the French mathematician and physicist Siméon Poisson, is the negative of the ratio of (signed) transverse strain to (signed) axial strain. For small values of these changes, {\displaystyle \nu } \nu is the amount of transversal expansion divided by the amount of axial compression..
