Section Modulus calculation and optimization

Section modulus:-

Section modulus is a direct measure of a strength of any cross sectional area of an object about an reference axis.

The formula of section modulus is given by,

S=I / Ymax

Where,
I = Moment of inertia (mm^4)
Y = Distance between neutral axes and outermost fiber (mm)

Steps to calculate section modulus:-

• Step 1:- Find location of centroid of given cross section.
• Step 2:- Find moment of inertia about neutral axis.

• Section modulus:-

  Steps to calculate section modulus:-

  • Step 1:- Find location of centroid of given cross section.
  • Step 2:- Find moment of inertia about neutral axis (INAINA)
  • Step 3:- Find YmaxYmax from neutral axis.
  • Step 4:- Find elastic section modulus using the formula provided above.
  

Conclusion

Strength of material is directly proportional to the moment of interia, thus increasing the sectional area increase the increases strength of component.

Thus sectional modulus for hood design is calculated and optimized design is also done to increase the section modulus of the hood.
