Section Modulus calculation and optimization

Section Modulus calculation and optimization

Section modulus:

Section modulus is the ratio of min moment of inertia to the distance between the neutral axis and the extreme end of the object

By section modulus we can identify how much load can take.

S = I / Y

Here

S = Section modulus

I = moment of inertia

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

SI Unit of Section Modulus is mm³

Using the Section from your Hood design and calculate the section modulus

This the Section from your Hood design

Case 1^st

Here

I = Min moment of inertia = 5.560195294e^+0.5(mm)

Y = the distance between the neutral axis and the extreme end of the hood = 243.02935

Calculating the section modulus (S)

S = I / Y

= 5.560195294e^+0.5/243.02935

= 0.4595 mm³

the section modulus (S) is 0.4594 mm³

Case 2^nd

Changing in depth of inner panel

After changing in depth, we got another MI

I = 5. 757773258e⁰³

Y = 243.0935

To find S,

S = I/Y

= 5.757773258e⁰³ / 243.0935

= 0.4758mm³

the section modulus (S) is 0.4758mm³

Conclusion:

After comparing Case 1^st and 2^nd we got to observe that as we change in depth of inner panel there is also change of moment of inertia so the section modulus also changes

As section modulus increases the strength of hood is increases
