OBJECTIVES:

• To learn fundamental concepts of Stress, Strain and deformation of solids with applications to bars, beams and thin cylinders.
• 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 analyse a complex two dimensional state of stress and plane trusses

UNIT I         STRESS AND STRAIN         9
Stress and strain at a point – Tension, Compression, Shear Stress – Hooke‟s Law – Relationship among elastic constants – Stress Strain Diagram for Mild Steel, TOR steel, Concrete – Ultimate Stress – Yield Stress – Factor of Safety – Thermal Stresses – Thin Cylinders and Shells – Strain Energy due to Axial Force – Resilience – Stresses due to impact and Suddenly Applied Load –
Compound Bars.

UNIT II           SHEAR AND BENDING IN BEAMS      9
Beams and Bending- Types of loads, supports – Shear Force and Bending Moment Diagrams for statically determinate beam with concentrated load, UDL, uniformly varying load. Theory of Simple
Bending – Analysis of Beams for Stresses – Stress Distribution at a cross Section due to bending moment and shear force for Cantilever, simply supported and overhanging beams with different loading conditions - Flitched Beams.

UNIT III         DEFLECTION        9
Double integration method - Macaulay's methods - Area moment method - conjugate beam method for computation of slopes and deflections of determinant beams.

UNIT IV        TORSION        9
Torsion of Circular and Hollow Shafts – Elastic Theory of Torsion – Stresses and Deflection in Circular Solid and Hollow Shafts – combined bending moment and torsion of shafts - strain energy
due to torsion - Modulus of Rupture – Power transmitted to shaft – Shaft in series and parallel –Closed and Open Coiled helical springs – Leaf Springs – Springs in series and parallel – Design of
buffer springs.

UNIT V COMPLEX STRESSES AND PLANE TRUSSES 9
2 D State of Stress – 2 D Normal and Shear Stresses on any plane – Principal Stresses and Principal Planes – Mohr's circle - Plane trusses: Analysis of plane trusses - method of joints - method of sections.

TOTAL (L:45+T:15): 60 PERIODS
