7. The longitudinal strain produced in a 1
wire is 0.375. Calculate lateral strain in
Poisson's ratio is 0.26.*
A. 9.75 x 10-2
B.9.75 x 10-3
C. 9.75 x 10-4
D. none of these​

Answer 1

Lateral strain is 9.75 × 10⁻²

Therefore option (A) is correct.

Explanation:

Given:

The longitudinal strain in a wire is 0.375

Poisson's ratio is 0.26

To find out:

The lateral strain in the wire

Solution:

We know that

If Poisson's ratio is $\nu$ then

$\text{Lateral Strain}=\nu\times\text{Longitudinal Strain}$

Here, $\nu=0.26$

And $\text{Longitudinal strain}=0.375$

Thus,

$\text{Lateral Strain}=0.26\times 0.375$

$\implies \text{Lateral Strain}=0.0975$

$\implies \text{Lateral Strain}=9.75\times 10^{-2}$

Hope this answer is helpful.
