Section Modulus calculation and optimization

OBJECTIVE

To calculate the section modulus for the hood design and optimization .to over come the new sketch an it used to improvr the section modules of the section

INTRODUCTION

Section modules is a geomentrical property for a given cross section usedin the design of beam ,torsion,bending movement ,etc other geomentical property used in sketch include area,with diameter,tention,radius etc an moment of inertia and polar moment of inertian for stiffes

TYPES OF SECTION MODULES

elastic section modules (S)

plastic section modules (Z)

ELASTIC SECTION MODULES

For general design the elastic modulses is used apply in yield point

the elastic modules is definede as = I/Y where i is the section modules of area

and Y is the distance of axis is often Y=C,where c is the distance from extreme fiber

PLASTIC SECTION MODULE

The plastic section modules depends on the location of the plastic neutral axis pna the pna os defined the axis the split the cross section such that the comprossion force from the area in compression equal the tention from the area in tention

HOOD DESIGN

S=I/Y

S=SECTION MODULE

I=MOMENT OF INERTIA

Y=DISTANCE BETWEEN THE NATURE OF AXIS AND EXTREME END OF THE OBJECT

M=THE MOMENT ABOUT NATUREAXIS

SECTION 1

SECTION 2

CONCLUSION

By using the values modulus of optimizing hood design 1 is increased by 2

moi decrease with the section area

moi decrease with the section length
