YOUR ANSWER : ?

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

1/4

1/2

1/3

TRUE ANSWER : ?
YOUR ANSWER : ?

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

All of these
