The graph below shows a function multiplied by constant factors 2 and 0 5 and the resulting vertical stretch and compression. Poisson s ratio is a measure of the poisson effect that describes the expansion or contraction of a material in directions perpendicular to the direction of loading the value of poisson s ratio is the negative of the ratio of transverse strain to axial strain for small values of these changes is the amount of transversal expansion divided by the amount of axial compression. How to do horizontal expansions or compressions in a function.
