MECHANICS OF SOLIDS
UNIT I - CONCEPT OF STRESSES AND STRAINS (12 hours)
Concept of stress and strain, Hooke's law - Tension, Compression, and
Shear, stressstrain diagram - Poisson's ratio, elastic constants and
their relationship - Deformation of simple and compound bars. Thermal
stresses – simple and Composite bars.Principal plane, principal
stress, maximum shearing stress - Uniaxial, biaxial state of stress -
Mohr's circle for plane stresses.
UNIT II - ANALYSIS OF BEAMS (12 hours)
Types of beams and loads - shear force and bending moment diagrams for
cantilevers, simply supported and over hanging beams. Theory of pure
bending -Bending stresses in simple and composite beams. Shear stress
distribution in beams of different sections.
UNIT III - TORSION OF SHAFTS (12 hours)
Theory of pure torsion, torsion of circular shafts and composite shafts.
UNIT IV - DEFLECTION OF BEAMS (12 hours)
Slope and deflection of cantilever, simply supported beam by double
integration method - Macaulay's method - Moment area method -
UNIT V - COLUMNS AND CYLINDERS (12 hours)
Columns and struts: Member subjected to combined bending and axial
loads, Euler's theory, Crippling load, Rankine's theory. Cylinders And
Shells: Thin cylinder,thin spherical shells under internal pressure -
Thick cylinders - Lame's equation -Shrink fit and compound cylinders.
