Pick up the correct statement from the following:
The moment of inertia is calculated about the axis about which bending takes place
If tensile stress is less than axial stress, the section experiences compressive stress
If tensile stress is equal to axial stress, the section experiences compressive stress
If tensile stress is more than axial stress, some portion of the section experiences a tensile stress
All the above.
