When a material is subjected to some force, its dimension changes in the direction of force applied. Due to the resulting effect of the longitudinal strain, a lateral strain (strain in the perpendicular direction of force applied) is also produced in the material.
This happens because of the constant mass of material i.e material quantity. Lateral dimension changes to sustain the constant amount of material.
The ratio of Lateral strain to Longitudinal strain is always constant for a particular material which is called 'Poisson's Ratio.' It is denoted by '𝒱'.

grt...basics things are in this thats good..

Fascinating take on Poisson's Ratio! Understanding how materials deform laterally under stress is crucial, especially in high volume pcb production. When boards undergo thermal or mechanical strain, micro-cracks can ruin yields. Balancing this ratio ensures structural integrity. Great breakdown of a vital engineering concept!
