Which of the following values of Poisson’s ratio can not be possible?
Show Hint
Poisson’s ratio is always within the range \( -1 \leq \nu \leq 0.5 \).
Updated On: Mar 26, 2025
- \( 0.3 \)
- \( -1.5 \)
- \( -0.8 \)
- \( 0.4 \)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Poisson’s ratio \( \nu \) is defined as:
\[ \nu = -\frac{\text{Lateral strain}}{\text{Longitudinal strain}} \] It is typically in the range \( -1 \leq \nu \leq 0.5 \) for stable materials. Since \( -1.5 \) falls outside this range, it is not possible.
\[ \nu = -\frac{\text{Lateral strain}}{\text{Longitudinal strain}} \] It is typically in the range \( -1 \leq \nu \leq 0.5 \) for stable materials. Since \( -1.5 \) falls outside this range, it is not possible.

- A wire of length \(100 \text{ cm}\) and area of cross-section \(2 \text{ mm}^2\) is stretched by two forces of each \(440 \text{ N}\) applied at the ends of the wire in opposite directions along the length of the wire. If the elongation of the wire is \(2 \text{ mm}\), the Young’s modulus of the material of the wire is:

- One end of a metal wire is fixed to a ceiling and a load of 2 kg hangs from the other end. A similar wire is attached to the bottom of the load and another load of 1 kg hangs from this lower wire. Then the ratio of longitudinal strain of the upper wire to that of the lower wire will be:\[\text{[Area of cross section of wire = 0.005 cm}^2, \, Y = 2 \times 10^{11} \, \text{N/m}^2, \, g = 10 \, \text{m/s}^2\text{]}\]

- A wire of cross-sectional area $A$, modulus of elasticity $2 \times 10^{11} \, \text{Nm}^{-2}$, and length $2 \, \text{m}$ is stretched between two vertical rigid supports.
When a mass of $2 \, \text{kg}$ is suspended at the middle, it sags lower from its original position making angle $\theta = \frac{1}{100}$ radian on the points of support.
The value of $A$ is ____ $\times 10^{-4} \, \text{m}^2$ (consider $x \ll l$).
