A) \[M\]
B) \[\sqrt{M}\]
C) \[{{M}_{2}}\]
D) \[\text{1/M}\]
Correct Answer: A
Solution :
Bending stress, \[\sigma =\frac{M}{z}\] For \[\sigma \] to remain constant, \[z\propto M\] For a rectangular beam of width b and depth h. \[z=\frac{b{{h}^{2}}}{6}\] \[\therefore \] \[b{{h}^{2}}\propto M\] For h=constant, \[b\alpha \,M\]You need to login to perform this action.
