A) F
B) 2F
C) \[\frac{F}{4}\]
D) 4F
Correct Answer: C
Solution :
Breaking stress \[=\frac{breaking\,force}{area}=\]constant \[\frac{F}{\left( \frac{\pi {{D}^{2}}}{4} \right)}=\frac{F}{\pi {{D}^{2}}}\] \[\frac{F}{\pi {{D}^{2}}}=4\frac{F}{\pi {{D}^{2}}}\] \[F=4F\] \[F=\frac{F}{4}\]You need to login to perform this action.
