Section Modulus calculation and optimization
SECTION MODULUS
AIM : to calculate the section modulus of the hood design by using catia v5 and improve the strength of the hood design.
section modulus
it gives and idea about how much of load the given structure can take OR if the section modulus increase the moment of resistance increase and hence its load design cqapacity OR ratio of total movment resisted by the section to the stress in the extreme fibre.
FORMULA
S= section modulus
I = movement of inertia
Y = distance between the neutreal axis and extrene and of the project.
section modulus part1

inertia part 1
minimum value = 1.594e-006m^4
= 1.594-006x10^12mm^4
= 1.594-006x10^12mm^4
maximum value = 5.643e-004m^4
= 5.643e-004x10^12mm^4
= 5.643e-004m^4
distance between the neutral axis and the extreme end of the object.

Y = 889.032/2
= 444.5mm
hence section modulus
S = I/Y
= 1.594x10^4-006/444.5
= 3586.0517mm^3
section modulus part 2

inertia part2
minimum value = 1.708e-006m^4
= 1.708e-006x10^12mm^4
= 1.708e-006m^4
maximum value = 5.936e-004m^4
= 5.936e-004x10^12mm^4
= 5.936e-004m^4
distance between the neutral axis and the extreme end of the object.

Y = 889.032/2
= 444.5mm
hence section modulus
S = I/Y
= 1.708e-006/444.5
= 3842.59mm^3
CONCLUSION
The section modulus of hood is 3586.0517mm^3 and increase the 0.5mm value it is 3842.59mm^3 . hence by increasing the value the section the strength of the hood increses
