A.
The moment of inertia is calculated about the axis about which bending takes place |
|
B.
If tensile stress is less than axial stress, the section experiences compressive stress |
|
C.
If tensile stress is equal to axial stress, the section experiences compressive stress |
|
D.
If tensile stress is more than axial stress, some portion of the section experiences a tensile stress |
|
E.
All the above. |
