Meaning of design: Definition and understanding of various types of design, Elaborated
Design process.
Design and creativity: Systematic design conceptualization, product design definition &
manufacturing considerations in design, underlying principles of design in Aesthetics and
ergonomics, free body diagram for components design.
General Design Considerations: Theory of Failure, Selection of materials, Basic criteria of
selection of material for automotive parts like piston, cylinder, connecting rod, crankshaft and
camshaft, mechanical properties of those materials in brief. Study of Stress concentration,
factor of safety under different loading conditions,
Design against Static Loading: Bolted Joints- Understanding the various stresses/ failure in
bolted joints, basic and eccentrically loaded bolts, Welded Joints- Design for various loading
conditions in torsion, shear or direct loads.
Design against Fluctuating Loading: Design of automobile coupling & Springs, Flywheel,
Braking Systems, self energizing brakes, shoe brakes - internal & external expanding, band
brakes and disc brakes.

clutch, energy dissipated, torque transmission capacity of clutch. Gears - Design of spur,
helical and straight bevel gears, Final Drive- Design consideration for different types of
propeller shafts & rear axles. Bearing - Basics of bearings, their types, nomenclature and
