Physics Elasticity Question 113
Question: For silver, Young’s modulus is $ 7.25\times 10^{10},N/m^{2} $ and Bulk modulus is $ 11\times 10^{10},N/m^{2} $ . Its Poisson’s ratio will be
Options:
A) ? 1
B) 0.5
C) 0.39
D) 0.25
Show Answer
Answer:
Correct Answer: C
Solution:
$ Y=3K(1-2\sigma ) $
$ \sigma =\frac{3K-Y}{6K} $ =$ \frac{3\times 11\times 10^{10}-7.25\times 10^{10}}{6\times 11\times 10^{10}} $
$ \Rightarrow \sigma =0.39 $
