Section Modulus calculation and optimization

SECTION MODULE--

Section modulus is a geometric property for a given cross-section used in the design of beams or flexural members. Other geometric properties used in design include area for tension and shear, radius of gyration for compression, and second moment of area and polar second moment of area for stiffness. Any relationship between these properties is highly dependent on the shape in question. Equations for the section moduli of common shapes are given below. There are two types of section moduli, the elastic section modulus and the plastic section modulus.

This is the formula for section modulus

S = I/y

 Where, 

S = Section Modulus

I = Moment of Inertia

y = distance between the neutral axis and the extreme end of the object 

CASE 1

S= I/Y

 = 2.88749 mm4 / 438mm

= 0.00659244mm3

CASE 2

S = I/Y

  = 2.93548 mm4 / 438mm

 = 0.006702 mm3
