n=critical neutral axis
m=modular ratio
c=permissible stress in concrete
t=permissible stress in steel.
We know that n=[mc/(mc+t)] *d.
= n/d=mc/(mc+t).
Now reciprocating both sides,
= d/n=(mc+t) /mc,
= d/n=1+t/mc,
= d/n-1=t/mc,
= (d-n)/n=t/mc.
Now reciprocating again to get the required expression i.e.
= n/(d-n) = mc/t.
m=modular ratio
c=permissible stress in concrete
t=permissible stress in steel.
We know that n=[mc/(mc+t)] *d.
= n/d=mc/(mc+t).

= d/n-1=t/mc,
= (d-n)/n=t/mc.

It will be mc/t =d/d-n.

On solving for the value of n.
ie. neutral axis, we will get n = (m * c *d)/(m*c+t).
ie. neutral axis, we will get n = (m * c *d)/(m*c+t).

Here,
t= permissible tensile stress in steel,
c= permissible compressive stress in concrete,
m=modular ratio.
t= permissible tensile stress in steel,
c= permissible compressive stress in concrete,
m=modular ratio.
