AERONAUTICAL ENGINEERING


STRENGTH OF MATERIALS




UNIT I - BASICS AND AXIAL LOADING                                                          

Stress and Strain – Hooke’s Law – Elastic constants and their relationship– Statically determinate cases - statically indeterminate cases –composite bar. Thermal Stresses – stresses due to freely falling weight.

UNIT II - STRESSES IN BEAMS                                                                           

Shear force and bending moment diagrams for simply supported and cantilever Beams-Bending stresses in straight Beams-Shear stresses in bending of beams with rectangular, I&T, etc. cross sections-beams of uniform strength

UNIT III - DEFLECTION OF BEAMS    

Double integration method – McCauley’s method - Area moment method – Conjugate beam Method-Principle of super position-Castigliano’s theorem and its application

UNIT IV –TORSION                                                                                              

Torsion of circular shafts - shear stresses and twist in solid and hollow circular shafts – closely coiled helical springs. –

UNIT V - BI AXIAL STRESSES                                                                            

Stresses in thin circular cylinder and spherical shell under internal pressure – volumetric Strain. Combined loading – Principal Stresses and maximum Shear Stresses - Analytical and Graphical methods.
