What are limiting values of poisson's ratio ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Poisson's Ratio**: Poisson's ratio (ν) is a measure of the ratio of transverse strain to axial strain when a material is subjected to uniaxial stress. It is defined as:
\[ \nu = -\frac{\text{Transverse Strain}}{\text{Axial Strain}} \]

2. **Theoretical Limits**: Theoretically, for homogeneous and isotropic materials, the limiting values of Poisson's ratio are:
