First we determine the moment of inertia

Here, the neutral axis would be at

$Y_{NA} = \frac{Σ_{i=1}^nA_iY_i}{Σ_{i=1}^n A_i}$

In the I-section,

No.	Section	Area $(A_i)$	Centroid Distance from the base of the section $(Y_i)$	$A_iY_i$
1	Upper flange	240 × 40 = 9600 $mm^2$	40 + 240 + $\frac{40}{2} = 300mm$	2880000 …
