Two simply supported beams A & B have the same length ‘L’ & subjected to equal bending moment M. The stress induced in the beam A & B are σA & σB respectively. If the cross-section of beam A is (b × b/2) & that of beam B is (b/2 × b), then the correct relation between σA & σB is:
1
σA = 2σB
2
σA = 4σB
3
σA = 0.5σB
4
σA = σB
