MECHANICS OF SOLIDS
UNIT – I
SIMPLE STRESSES & STRAINS : Elasticity and plasticity – Types of stresses & strains–Hooke’s law
– stress – strain diagram for mild steel – Working stress – Factor of safety – Lateral strain, Poisson’s ratio
& volumetric strain – Elastic moduli & the relationship between them – Bars of varying section – composite
bars – Temperature stresses.Strain energy – Resilience – Gradual, sudden, impact and shock loadings.
UNIT – II
SHEAR FORCE AND BENDING MOMENT : Definition of beam – Types of beams – Concept of shear
force and bending moment – S.F and B.M diagrams for cantilever, simply supported and overhanging
beams subjected to point loads, u.d.l., uniformly varying loads and combination of these loads – Point of
contra flexure – Relation between S.F., B.M and rate of loading at a section of a beam.
UNIT – III
FLEXURAL STRESSES : Theory of simple bending – Assumptions – Derivation of bending equation: M/
I = f/y = E/R Neutral axis – Determination bending stresses – section modulus of rectangular and circular
sections (Solid and Hollow), I,T,Angle and Channel sections – Design of simple beam sections.
UNIT – IV
SHEAR STRESSES : Derivation of formula – Shear stress distribution across various beams sections
like rectangular, circular, triangular, I, T angle sections.
UNIT – V
ANALYSIS OF PIN-JOINTED PLANE FRAMES : Determination of Forces in members of plane, pinjointed,
perfect trusses by (i) method of joints and (ii) method of sections. Analysis of various types of
cantilever& simply–supported trusses-by method of joints,method of sections & tension coefficient methods.
UNIT – VI
DEFLECTION OF BEAMS : Bending into a circular arc – slope, deflection and radius of curvature –
Differential equation for the elastic line of a beam – Double integration and Macaulay’s methods –
Determination of slope and deflection for cantilever and simply supported beams subjected to point loads,
- U.D.L uniformly varying load. Mohr’s theorems – Moment area method – application to simple cases
including overhanging beams.
UNIT – VII
THIN CYLINDERS : Thin seamless cylindrical shells – Derivation of formula for longitudinal and
circumferential stresses – hoop, longitudinal and Volumetric strains – changes in dia, and volume of thin
cylinders – Riveted boiler shells – Thin spherical shells.
UNIT – VIII
Thick cylinders–lame’s equation – cylinders subjected to inside & out side pressures – compound cylinders.
