Question

Poisson's ratio... a) is a method to relate the longitudinal deformation of a material with its simultaneous lateral deformation b) ..is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space c) is a dimensionless number equal to the change in length of a specimen, divided by the original length d) .typically has low values for polymers, and high values for metals

Answer 1

Answer:

The Poisson's ratio (ν) is a method to relate the longitudinal deformation of a material with its simultaneous lateral deformation.

Explanation:

The Poisson's ratio (ν) is a method to relate the longitudinal deformation of a material with its simultaneous lateral deformation.

It can be expressed as

$\nu=-\frac{\epsilon_{trans}}{\epsilon_{long}}$

It is a measure of the Poisson effect, in which a material tend to expand in directions perpendicular to the direction of compression.
