Section Modulus calculation and optimization
Section 1


Here I = 2.67x10^4
Y = 0.088x10^4 (879.8288mm)
There for Z1 = I/Y
=2.67x10^4/0.088x10^4
= 30.34
Section 2


Here I = 2.71x10^4
Y = 0.088x10^4
There for Z2 = I/Y
= 2.71x10^4/0.088x10^4
= 30.79
While comparing Z1 & Z2
Z2 > Z1
by offseting a 0.5mm if inner hood pannel the section moduless of the hood is incresed.
