1) When NA lies in flange then;
The stress block dig above NA is a rectangular parabola. So stress distribution is linear
TF= 0.87fy.Ast.
CF= 0.36.fck.bf.
(2) when NA falls in Web.
Stress in the flange is not uniform so analysis becomes difficult;
-Stress changes the constant value after the depth (3/7).

When the neutral axis lies within the flange then we design the beam as a singly reinforced section.

When the neutral axis lies in the flange section, not in the web we have to design it as a simple rectangular beam as the compression block is limited in the flanges.

When the neutral axis remains in a flange, the lower part of N.A we do not consider in design so the upper part of N.A is like a rectangular.
