Pick up the correct statement from the following: 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

The correct answer is: D. All the above

The moment of inertia is a measure of the resistance of a cross-section to bending. It 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 no stress.

The moment of inertia is a property of the cross-section of a beam. It is calculated about an axis that passes through the centroid of the cross-section. The moment of inertia is a measure of the resistance of the cross-section to bending. The larger the moment of inertia, the more resistant the cross-section is to bending.

Tensile stress is the stress that is caused by a tensile force. Tensile stress is a positive stress. Compressive stress is the stress that is caused by a compressive force. Compressive stress is a negative stress.

If tensile stress is less than axial stress, the section experiences compressive stress. This is because the tensile stress is trying to pull the section apart, while the axial
