Section Modulus calculation and optimization
Section modulus(S)
section modulus is a direct measurement of strength of an section area of an object about an reference axis
strength is nothing but capability of supporting greater load during accidents.
Moment of inertia (I)
Moment of inertia is a offering resistance to the movement like bending , twisting or any extrarenal load.
Total Linear distance of section (L)
Section Modulus
S=I/Y


CASE 1
I=1.57285*10^04mm^4
Y=L/2
L=880.9mm
Y=880.9/2=440.45
S= 1.57285*10^04/440.45=35.71mm^3


CASE 2
I=1.58112687*10^04mm^4
Y=L/2
L=880.9mm
Y=880.9/2=440.45
S= 1.58112687*10^04/440.45=35.89mm^3
Comparing to case 1 the case 2 had a more section modulus value that menace case 2 had good structural strength than case 1 section.
