Two simply supported beam A and B has the same length L and subjected to equal bending moment M. The stress induced in the beam A and B are ${\mathit{\sigma }}_{\mathit{A}}$ and ${\mathit{\sigma }}_{\mathit{B}}$ respectively. If the cross section of beam A is $\mathit{b}\times \frac{\mathit{b}}{2}$ and that of beam B is $\frac{\mathit{b}}{2}\times \mathit{b}$ , then correct relation between ${\mathit{\sigma }}_{\mathit{A}}$ and ${\mathit{\sigma }}_{\mathit{B}}$ is
