9. If the load on beam is increased, the tensile stress in the concrete below the neutral axis will-
Explained: When load on the reinforced concrete beam is small so that the tensile stress set up in the concrete below the neutral axis is smaller than the permissibble, then the concrete area the neutral axis will not crack/

1. The property of a fluid which enables it to resist tensile stress is known as-Cohesion
2. The ratio of the length and depth of a simply supported rectangular beam which experiences maximum bending stress equal to tensile stress, due to same load at its mid span, is-2/3
3. The ratio of the length and diameter of a simply supported uniform circular beam which experiences maximum bending stress equal to tensile stress due to same load at its mid span, is-1/2
When equal and opposite forces applied to a body, tend to elongate it, the stress so produced, is called- Tensile stress
