Chapter 7: Problem 937

The poisson's ratio cannot have the value.......... (A) \(0.7\) (B) \(0.2\) (C) \(0.1\) (D) \(0.5\)

Short Answer

Expert verified
The Poisson's ratio cannot have the value 0.7 because it lies outside the typical range of \(-1 \leq ν \leq 0.5\). The answer is (A).

Step by step solution

01

Recall the range for Poisson's ratio

We know that Poisson's ratio usually lies between -1 and 0.5. The range is given by: \(-1 \leq ν \leq 0.5\)
02

Compare the given values with the range

Now, let's compare the four given values to this range to see whether they lie within it or not. (A) 0.7 (B) 0.2 (C) 0.1 (D) 0.5
03

Determine the invalid value for Poisson's ratio

Comparing the given values to the range of Poisson's ratio, we find that the value 0.7 (A) lies outside the range, whereas the other three values lie within the acceptable range. Therefore, the Poisson's ratio cannot have the value 0.7. The answer is (A).
