Section Modulus calculation and optimization

Title : Section Modulus calculation and optimization

Objective :

Use the Section from your Hood design and calculate the section modulus using the formula S = I/y

S = Section Modulus

I = Moment of Inertia

Y = distance between the nuteral axis and the extreme end of the object

Section Modulus calculation and optimization

Section Modulus indicates Strength of material.

If section modulus is Larger then the material is stronger.

According to this section give below in Fig 1

The section Modulus is define as

S= I/y

I =Min Moment of inertia = 1.637mm^4

Y = distance from neutral axis to any axis= 904/2=452 mm

Section Modulus S = I/y = 1.637/452 = 0.0063 mm^3

Now to Increase section Modulus we need to increase distance between Hood Inner panel and Outer Panel.

As per fig 2

I = 7.29mm^4

y=452mm

Section Modulus = 7.29/452=0.16mm^3

As we know greater the section modulus better is the strength of material

Conclusion : As per above analysis as we increase distance between inner and outer panel Moment of interia will increase and simultaneously section Modulus will increase.
