Stresses in axial members: Normal stress – St. Venant’s principle – normal strain – tension and compression test – stress and strain diagrams – factor of safety – Hooke’s law. Axial deformation – principle of superposition – lateral strain – Poisson’s ratio – shear stress and strain – shear modulus – volumetric strain – bulk modulus – relation between elastic constants. Stresses in joints – shear and bearing stresses – temperature stress and strain – stress concentration.
Stresses in transverse members: Isolation of beam element – intensity of load, shear force and bending moment relation – shear force and bending moment diagrams – bending stresses in transverse members – Euler – Bernoulli’ s simple beam theory – bending stress distribution – shear stresses in transverse members – shear stress distribution.
Deflection in transverse members: Moment-curvature relation – double-integration, Macaulay’s – conjugate beam – propped cantilever – fixed beams. Stresses in torsional members: Torsional shear stress – torsion equation for circular section – polar moment of inertia – torsional deformation – stresses due to combined loading.
