Section Modulus calculation and optimization

section modulus:

• the ratio of the bending resisted by the section to the stress in the extreme fiber

why do we calculate section modulus?

• it is calculated so that we can know the stiffness and rigidity of the part/the component
• to make sure that we are optimizing our part to get the maximum stiffness and rigidity possible

formula:

`S=I/Y`

where

• `S = "Section modulus"`
• `I = " Moment of Inertia "`
• `y = " distance between the neutral fiber and the extreme fiber"`

`S = (1.796xx10^6 mm^4)/(239.0345 mm)`

`S = 7513.5597 mm^3`

How to improve section modulus?

to improve section modulus there are multiple ways

1. to increase the thickness of the material

2. to increase the cross-sectional area of the component

3. to increase the height of the stress structure (embosses)

4. to change the center of gravity by attaching weights (external solution) or adding reinforcements
