If the depth of actual neutral axis of a doubly reinforced beam

Is equal to the depth of critical neutral axis; the concrete and steel attain their maximum stresses simultaneously
Is less than the depth of critical neutral axis, the steel in the tensile zone attains its maximum stress earlier
Is greater than the depth of critical neutral axis, the concrete attains its maximum stress earlier
