A uniform cubical block is subjected to volumetric compression, which decreases its each side by $2\%$. The Bulk strain produced in it is

The Poisson's ratio cannot have the value,

Figure shows graph between stress and strain for a uniform wire at two different temperatures. Then

Two different types of rubber are found to have the stress-strain curves as shown. Then

The stress-strain graphs for two materials $A$ and $B$ are shown in figure. The graphs are drawn to the same scale. Select the correct statement
