OBJECTIVES

 To learn the fundamental concepts of Stress, Strain and deformation of solids.
 To know the mechanism of load transfer in beams, the induced stress resultants and
deformations.
 To understand the effect of torsion on shafts and springs.
 To analyze plane and space trusses

UNIT I STRESS, STRAIN AND DEFORMATION OF SOLIDS
Simple Stresses and strains – Elastic constants – Relationship between elastic constants – Stress
Strain Diagram – Ultimate Stress – Yield Stress – Deformation of axially loaded member –
Composite Bars – Thermal Stresses – State of Stress in two dimensions – Stresses on inclined
planes – Principal Stresses and Principal Planes – Maximum shear stress – Mohr’s circle method.

UNIT II TRANSFER OF LOADS AND STRESSES IN BEAMS
Types of loads, supports, beams – concept of shearing force and bending moment – Relationship
between intensity of load, Shear Force and Bending moment – Shear Force and Bending Moment
Diagrams for Cantilever, simply supported and overhanging beams with concentrated load,
uniformly distributed load, uniformly varying load and concentrated moment. Theory of Simple
Bending – Stress Distribution due to bending moment and shearing force – Flitched Beams – Leaf
Springs.

UNIT III DEFLECTION OF BEAMS
Elastic curve – Governing differential equation – Double integration method – Macaulay’s method –
Area moment method – conjugate beam method for computation of slope and deflection of
determinant beams.

UNIT IV TORSION
Theory of Torsion – Stresses and Deformations in Solid and Hollow Circular Shafts – combined
bending moment and torsion of shafts – Power transmitted to shaft – Shaft in series and parallel –
Closed and Open Coiled helical springs – springs in series and parallel – Design of buffer springs.

UNIT V ANALYSIS OF TRUSSES
Determinate and indeterminate trusses – Analysis of pin jointed plane determinate trusses by
method of joints, method of sections and tension coefficient – Analysis of Space trusses by
tension coefficient method.
