A) 1 : 16
B) 16 : 1
C) 1 : 64
D) 64 : 1
Correct Answer: B
Solution :
\[\text{strain}\propto \text{stress}\propto \frac{\text{F}}{\text{A}}\] Ratio of strain =\[\frac{{{A}_{2}}}{{{A}_{1}}}={{\left( \frac{{{r}_{2}}}{{{r}_{1}}} \right)}^{2}}={{\left( \frac{4}{1} \right)}^{2}}=\frac{16}{1}\]You need to login to perform this action.
