MACHINE ELEMENTS AND MACHINING
1. STRESSES IN MACHINE ELEMENTS
Stresses in simple machine members - axial, bending, torsional, bearing stress, Hertz contact stress; combined stresses, principle stresses, theories of failure, factor of safety, stress concentration, preferred numbers.
2. DESIGN OF SHAFTS AND WELDED JOINTS
Shaft design subjected to bending forces due to belts, chains and gears, torsion; welded joints - types of welding symbols, design of welded joints subjected to various types of loads.
3. DESIGN OF MACHINE ELEMENTS
Design of springs, couplings and selection of bearings.
4. TRANSMISSION ELEMENTS
Gears: spur, helical, bevel and worm gears - Nomenclature, materials and gear forces; design of belts-selection of V-belts and chain drives.
5. MACHINING PROCESSES - AN OVERVIEW
Types of Machining Operation, cutting tool materials and tool life; Non-traditional machining processes - USM, ECM, EDM, chemical milling - an introduction.
