engineering recuitment NHPC JE & THDC JE 2023 Mock Test Strength of Materials Shear Stress and Bending Stress
A beam cross-section is used in two different orientations as shown in figure given below:
Bending moments applied to the beam is both cases are same. The maximum bending stresses induced in case (A) and (B) are related as:
1
σA = σB
2
σA = 2 σB
3
\({{\rm{\sigma }}_A} = \frac{{{{\rm{\sigma }}_B}}}{2}\)
4
\({{\rm{\sigma }}_A} = \frac{{{{\rm{\sigma }}_B}}}{4}\)
