Liquids have no Poisson's ratio,because

If the volume of a wire remains unchanged when it is stretched,what is the Poisson's ratio for the wire?

The minimum and maximum values of Poisson's ratio for a metal lie between

In materials like aluminium and copper, the correct order of magnitude of various elastic moduli is:

$A 3 \ m$ long steel wire is stretched to increase its length by $0.3 \ cm$. Poisson's ratio for steel is $0.26$. The lateral strain produced in the wire is

$A$ uniform wire of length $10 \ m$ and diameter $0.6 \ mm$ is stretched by $6 \ mm$ with a certain force. If the Poisson's ratio of the material of the wire is $0.3$,then the change in diameter of the wire is
