Section Modulus calculation and optimization

Section Modulus: Ratio of Moment of inertia at the neutral axis to the farthest point from neutral axis

It gives the strength of the hood based on the intersection given at midpoint

So, in the given zip file i have mentioned intersections at different lengths having diiferent moment of inertia. Higher the minimum moment of inertia higher the strength

so, here in this example we choosen inertsection at 50% of hood lenght and performed section inertia analysis. And we have changed the master section lenght of 25 to 24.5 and done the same section inertia analysis.I have observed that a change in minimum moment of inertia.
