If Poisson's ratio

\sigma

for a material is

-\frac{1}{2}

, then the material is

View answer and explanation

Correct option: B

incompressible

Option B is correct. A Poisson's ratio of -1/2 indicates that the material's volume remains constant under deformation, which is the definition of incompressibility.
