INSTRUCTIONAL OBJECTIVES
Resolution of forces and to comprehend the various forces (Internal and External) and their action on
different structural elements and determine the stresses and strains
Awareness on the properties of plane areas
To analyse and determine the internal forces in pin jointed plane trusses by various methods
To study the behaviour of determinate beams and examine the internal forces, stresses induced and
learn the theory of torsion and stresses developed in solid, hollow shafts and helical springs.
To analyse the state of stress (two dimensional) and evaluate the principal stresses and principal
planes by analytical and graphical treatment.
BASICS OF MECHANICS, STRESS, STRAIN AND DEFORMATION OF SOLIDS
Vectors-Concept of forces-Concept of particle and rigid body -Non-concurrent and parallel forces in a
plane - Moment of force and Varignon's theorem -Free body diagram-conditions of equilibrium-
Principle of virtual work-equivalent force system. Rigid bodies and deformable solids - tension,
compression and shear stresses - strain - Lateral strain - Poisson's ratio - Volumetric strain -
Deformation of simple and compound bars - Elastic constants - Composite sections - Thermal stresses -
Thin Cylinders and spherical Shells - Deformation of thin Shells - Stresses at a point in thin Shells.
CENTRE OF GRAVITY AND MOMENT OF INERTIA
Areas and volumes - Theorems of Pappus and Guldinus - Centroid of simple areas and volumes by
integration - centroid of composite areas - Second and product moment of areas - radius of gyration -
parallel axis and perpendicular axis theorems - moment of inertia of simple areas by integration
-moment of inertia of composite areas - mass moment of inertia of thin plates and simple solids.
ANALYSIS OF STATICALLY DETERMINATE PLANE TRUSSES
Stability and Equilibrium of plane frames - Perfect frames - Types of Trusses - Analysis of forces in
truss members - Method of joints - Method of Sections - Tension Co-efficient method - Graphical
method.
BENDING OF BEAMS AND TORSION OF SHAFTS
Beams - types of Support - Types of load - S.F and B.M in beams - Cantilevers, Simply supported and
