Poissons Ratio

Out of Rubber/Steel/Wood, which have higher Poissons Ratio?

Verified

When material is compressed in one direction, it automaitcally tends to expand within the other two directions that is perpendicular to the direction of compression. This mechanism is known as the Poisson effect. Poisson’s ratio is defined as a measure of Poisson effect.

For rubber = 0.5

For steel = 0.288

For wood < 0.2

Hence, the Poisson’s ratio is higher in the RUBBER.
