# How to study this subject

OBJECTIVE
The subject of Mechanics of Solids cuts broadly across all branches of engineering profession.
At the end of this course, the student will have knowledge about behaviour of members
subjected to various type of forces. The subject can be mastered best by solving numerous
problems.
UNIT I STRESS STRAIN AND DEFORMATION OF SOLIDS, STATES OF STRESS 9+3
Rigid bodies and deformable solids  stability, strength, stiffness  tension, compression and
shear stresses  strain, elasticity, Hookes law, limit of proportionately, modules of elasticity,
stress-strain curve, lateral strain  temperature stresses  deformation of simple and compound
bars  shear modulus, bulk modulus, relationship between elastic constants  biaxial state of
stress  stress at a point  stress on inclined plane  principal stresses and principal planes 
Mohrs circle of stresses.25
UNIT II ANALYSIS OF PLANE TRUSS, THIN CYLINDERS / SHELLS 9+3
Stability and equilibrium of plane frames  types of trusses  analysis of forces in truss
members method of joints, method of sections, method of tension coefficients  thin cylinders
and shells  under internal pressure  deformation of thin cylinders and shells.
Beams  types of supports  simple and fixed, types of load  concentrated, uniformly
bending moment and shear force  bending moment, shear force diagram for simply supported,
cantilever and over hanging beams  Theory of simple bending  analysis of stresses  load
carrying capacity of beams  proportioning of sections
UNIT IV DEFLECTION OF BEAMS AND SHEAR STRESSES 9+3
Deflection of beams  double integration method  Macaulays method  slope and deflection
using moment area method, Conjugate Beam method  variation of shear stress  shear stress
distribution in rectangular, I sections, solid circular sections, hollow circular sections, angle and
channel sections  shear flow  shear centre.
UNIT V TORSION AND SPRINGS 9+3
Stresses and deformation in circular (solid and hollow shafts)  stepped shafts  shafts fixed at
both ends  leaf springs  stresses in helical springs  deflection of springs.
