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. All the above

A. The bending stress in a section is zero at its neutral axis and maximum at the outer fibres B. The shear stress is zero at the outer fibres and maximum at the neutral axis C. The bending stress at the outer fibres, is known as principal stress D. All the above
