A) Zero
B) \[40\,\,kgf\text{/c}{{\text{m}}^{\text{2}}}\]
C) \[60\,\,kgf\text{/c}{{\text{m}}^{\text{2}}}\]
D) \[80\,\,kgf\text{/c}{{\text{m}}^{\text{2}}}\]
Correct Answer: C
Solution :
\[{{\tau }_{N.A}}=\frac{3}{2}{{\tau }_{mean}}=\frac{3}{2}\times \frac{2000}{10\times 5}\] \[=60\,\text{kgf/c}{{\text{m}}^{\text{2}}}\]
