Principles of statics: Introduction to vector approach – free body diagram – forces in plane and space – concurrent forces – resolution of forces – equilibrium of particle. Statics of rigid bodies in two and three dimensions – moment of force – rigid body equilibrium – support reactions. Centroid and centre of gravity; Centroids of lines, areas, volumes and composite bodies – Second moment of area – polar moment of inertia – mass moment of inertia.
Simple Stresses and Strains: Hooke’s law – Elastic limit linear strain – lateral strain – Analysis of varying sections – bars of composite sections – Thermal stresses. Shear force and bending moment; Different types of support conditions and loads – Cantilever – simply supported – Over hanging beams, point loads, uniformly distributed loads – Theory of Simple bending; flexural formula.
Torsion of circular sections; Derivation of torsional formula – Assumptions made Power transmitted – Solid and hollow shafts. Complex stress; principal stresses and principal planes – principal strains – graphical method. Thin Shells; Thin cyclindrical shells subjected to internal pressure – Circumferential stress – Longitudinal stress – change in diameter – length-volume – Thin spherical shells. Columns; Axially loaded Columns – Different end conditions – Euler’s formula for long columns.
