Section Modulus calculation and optimization

SECTION MODULUS

section modulus is a geometric property for a given cross-section used in the design of beams or flexural members. Other geometric properties used in design include area for tension and shear, radius of gayration for compression, and moment of inertia and polar moment of inertia for stiffness

S=I/Y

s= section modulus

I = the moment of inertia

y = distance between netral axis and the end of object

MOMENT OF INERTIA

it is used insectional mechanical application usally involving a section of any structure

when the area of section increase moment of inertia also increase so the final result which is the section modulus also increase

OBJECTIVE

to find section modulus of the hood and optimize the section modulus value using nx cad

SECTION MODULUS OF HOOD 1

CALCULATION

s=i/y

i = 1.508294751e4 mm4

y = 439.231 mm

s = 34.3394 mm3 this is the section modulus value of the hood section

SECTION MODULUS OF HOOD 2

S=I/Y

I = 2.781773888E5mm4

Y = 439.231mm

S = 633.32 mm3
