Introduction to elastic response – stresses (tensile, compressive, shear & bending) & strength – strain and deformation, stress-strain curve for steel. Stresses and deformation of simple and compound bars under axial loads - Elastic constants and their relations-Thermal stresses and creep. Experiment : Tensile test on mild steel

Principal stresses – Introduction, significance, calculation of principal stresses - Mohr’s circle to find principal stresses. Strain energy in gradually applied loads, suddenly applied loads and Impact loads. Experiment: Determination of ultimate shear strength of steel by double shear test.

Types of beams: supports and loads – Cantilever, Simply supported and Overhanging beams - Shear force and bending moment diagrams. Stresses in beams – theory of simple bending and its applicability for actual conditions effect of shape of beams on stress induced - Bending stresses in simple and composite beams. Experiment : Microscopic Examination of Metal specimen

Elastic curve– Evaluation of beam: Double integration method & Macaulay’s method. Columns: End conditions, equivalent length – Euler’s equation and its limitations – slenderness ratio – Rankine’s formula for columns. Experiment : Deflection test on Beams , Impact test on mild steel specimen

Analysis of torsion of circular bars – shear stress distribution – twist and torsional stiffness – Bars of solid and hollow circular sections. Thin cylinders and shells – Hoop stress and longitudinal stresses. Experiment : Microscopic Examination of Metal specimen, Torsion test on mild steel specimen.
