If the depth of actual neutral axis of a doubly reinforced beam
is greater than the depth of critical neutral axis, the concrete attains its maximum stress earlier
is less than the depth of critical neutral axis, the steel in the tensile zone attains its maximum stress earlier
is equal to the depth of critical neutral axis, the concrete and steel attain their maximum stresses simultanesouly
all the above.

The length of the straight portion of a bar beyond the end of the hook, should be at least
twice the diameter
thrice the diameter
four times the diameter
five times the diameter
seven times the diameter.

A simply supported beam , 6 m long and of effective depth 50 cm, carries a uniformly distributed load 2400 kg/m including its self weight. If the lever arm factor is 0.85 and permissible tensile stress of steel is 1400 kg/cm2, the area of steel required, is
14 cm2
15 cm2
16 cm2
17 cm2
18 cm2
