A) \[+\frac{2}{3}\]
B) \[-\frac{1}{4}\]
C) \[+\frac{1}{4}\]
D) \[-\frac{2}{3}\]
Correct Answer: B
Solution :
Young's modulus, \[Y=\frac{3\eta }{2}\] We know that \[Y=2\eta (1+\sigma )\] \[\therefore \] \[\frac{3\eta }{2}=2\eta (1+\sigma )\] \[\Rightarrow \] \[\sigma =-\frac{1}{4}\]You need to login to perform this action.
