SOLID MECHANICS




UNIT I BASICS AND AXIAL LOADING 10

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 10

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 10

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 5

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



UNIT V BI AXIAL STRESSES 10

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.
