Section Modulus calculation and optimization

Y= 879.775 mm OR 0.879775 m

I1=0.000000243 m^4

I2=0.000000244 m^4

S1=I1/Y

S1=0.000000243/0.879775 m^3 OR 0.000000276 m^3

S2=I2/Y

S2=0.000000244/0.879775 m^3 OR 0.000000277 m^3

Section Modulus is a geometric property used in the desinging second moment of inertia or area moment of inertia is used show the stiffnes of the component.

We can change section modulus by changing MOI or by changing Y. we can change MOI by changing cross-section without changing Dimensions.

here i changed the MOI by offseting my hood inner panel and my MOI increased from 0.000000243 m^4 to o.oooooo244 m^4. in this way my section modulus also increased as i kept the Y constant.
