A material with a Poisson's ratio of 0.5 is considered to be:

Step 1: Understand what Poisson's ratio is. It measures how much a material deforms in one direction when it is stretched or compressed in another direction.
Step 2: Know the range of Poisson's ratio values. It typically ranges from -1 to 0.5 for most materials.
Step 3: Recognize that a Poisson's ratio of 0.5 means that when the material is stretched, it does not change in volume.
Step 4: Conclude that a Poisson's ratio of 0.5 indicates that the material is incompressible, meaning it cannot be compressed or expanded in volume.

Poisson's Ratio – A measure of the ratio of transverse strain to axial strain in a material when it is deformed.
Incompressibility – A property of materials that do not change in volume when subjected to pressure.
