About Book:

  We are pleased to bring out our first edition “Design of Machine Elements” for Engineering and Technology studies. This book is based on the latest Anna University syllabus of Mechanical Engineering branch for all engineering colleges. At the tail end of this book Anna University Solved questions papers have been added, which will enable the students to understand the question pattern.

Unit I deals with basic steady and variable stresses in machine members in which factor influencing mechanic design, selection of materials based on mechanical properties, direct, Bending and torsional stress equations, Impact and shock, eccentric loading, Design of curved, theories of failure are discussed. Elaborate treatment of analytical and theoretical nature is provided in all topics.

Unit II has an in depth dealing of design of solid and hollow shafts based on strength, rigidity and critical speed, design of keys and keyways, design of rigid and flexible couplings, introduction to gear and shock absorbing couplings, design of knuckle joints etc,

Unit III deals with the design of threaded fasteners, design of bolted joints including eccentric loading, design of welded joints for pressure vessels and structures, and theory of bonded joints

Design of helical, leaf, disc and torsional springs under constant loads and varying loads, concentric torsion springs, Belleville springs, design of levers have been discussed in Unit IV

Design of bearings, sliding contact and rolling contact types, cubic mean load, design of journal bearings, Mckees equation, Lubrication in journal bearings, design of flywheels involving stresses in rim and arm are treated elaborately with good examples in Unit V.
