Section Modulus calculation and optimization

AIM: To generate the report on finding the section modulus for the Hood design and improve its strength by optimization.

SECTION MODULUS: It is a geometric property for a given cross-section used in the design of beams or flexural members

If the section modulus increases the moment of resistance increases and its load on body bearing capacity.

Analyzing

Using the formula

S=I/Y

Where

S= section modulus

I = Moment of inertia

Y = Distance between Neutral axis and the extreme end of the hood.

Now, Analyzing from Intersect option we extract the inner hood and outer hood lines which is section of hood

Distance = 877.78mm

Y= 438.89mm

Analysing the Hood Design

We are taking the minimum value of Inertia = 2.3066X 10⁵ mm⁴

`s=(2.3066X〖10〗^5)/438.89`

`S=534.40 mm3`

Analyzing case 2

The case is analyzed by improving the section. Lifting the Emboss value

Improving the middle portion we get analysis of

Similarly considering the minimum value of Inertia = 2.3171X10⁵ mm⁴

`S=(2.3171X〖10〗^5)/438.89`

S= 527.79 mm⁴

These calculation are necessary to know the design actual withstand capability of product. As we increase the section area the moment of inertia and section modulus increases it means capacity of material also increases
