Yes, right @Pawan.

Critical neutral axis is the neutral axis at a balanced state, usually found through similar triangles using the modular ratio.
Actual neutral axis is found by assuming tensile and compressive moments are equal.
If actual < critical, the beam is under-reinforced.
If actual > critical, the beam is over-reinforced.
Actual neutral axis is found by assuming tensile and compressive moments are equal.
If actual < critical, the beam is under-reinforced.
If actual > critical, the beam is over-reinforced.

The neutral axis is an axis in the cross-section of a beam or shaft along which there are no longitudinal stresses or strains.
