Section Modulus calculation and optimization
SECTION MODULUS
It is the ratio between moment of inertia of the beam cross section about the neutral
to the distance of extreme fiber from the neutral axis
Section modulus is a geometric property for a given cross-section used in the design of beams or flexural members
S = I/Y
Where
I = moment of inertia
Y = distance of the extreme fibre from the neutral axis
AIM
To calculate the section modulus for the created hood design and modify the design to
increase the strength
DESIGN 1


for the first design first the moment of inertia value I= 2.868e+5 mm^4
the measured distance of the extreme fibre is L = 875.30mm So, Y = L/2
Y = 437.65mm
SECTION MODULUS FOR DESIGN 1 S= 2.868e+5/437.65
= 655.3mm^3
DESIGN 2


The moment of inertia for the 2nd Design I = 3.461e+5 mm^4
SECTION MODULUS FOR DESIGN 2
S = 3.461e+5/437.65
= 790.81mm^3
By comparing the design 1& 2
The design 2 is having high moment of inertia by comparing design 1
CONCLUSION
By increasing the distance between the inner panel and outer panel we will get more strength.
