General consideration in machine design-strength properties of engineering materials. Limits and tolerances- types of fits-simple stresses in machine elements-tension-compression-shear and bearing stresses. Torsional and bending stresses in machine parts- torsional stresses in shafts, bending stresses in beams. Theories of failure-Rankine’s theory, Guest theory, Saint Venants theory and Von Mises theory.

Design of permanent joints-welded joints-types of welded joints-transverse and parallel strength of fillet welds-design of butt joints-design of threaded fasteners-stresses in screwed fastening due to static loading.

Keys and couplings-strength of sunk keys- shaft couplings-design of sleeve coupling and flange coupling. Design of cotter and knuckle joints-design of shafts-shafts subjected to torsion, bending and combined stresses.

Linkages-basic definitions-different types of mechanisms and their applications-instantaneous center of rotation for four bar mechanisms-determination of velocities in 4 bars and slider crank mechanism-acceleration in mechanisms. Flywheel –fluctuation of speed and energy- energy stored in flywheel.

Gears-classification-gear terminology-law of gearing-design of spur and bevel gear based on Lewis and Buckingham equation. Springs-types of springs-design of helical springs. Belt drives-flat belts-Euler’s formula-V-belt design-power calculation and selection-chain drive-components-design.
