While writing the book,we have continuously kept in mind the examination requirments of the students preparing for U.P.S.C.(Engg. Services)and A.M.I.E.(I)examinations.In order to make this volume more useful for them,complete solutions of their examination papers up to 1975 have also been included.Every care has been taken to make this treatise as self-explanatory as possible.The subject matter has been amply illustrated by incorporating a good number of solved,unsolved and well graded examples of almost every variety.

The subject theory of machines forms the basis for understanding the working principles of a machine. The theoretical principles involved in machines have immediate application to practical problems. Designed as a text for the undergraduate students of mechanical engineering, it covers all the basics of mechanism and machine theory in a simple and logical manner. The basic theory presented in the book has been evolved out of simple and readily understood principles. The text begins with the discussion on various types of mechanisms and their working principles. Further it discusses the working of Oldham’s coupling, automobiles steering gears, engine pressure indicators, and estimation of velocity and acceleration using relative velocity method, complex algebra method and instantaneous centre method. Types of friction and power transmission by belt drives are also explained in detail. Finally it concludes with cam and follower mechanism. KEY FEATURES : Balanced presentation of the graphical and algebraic approaches Numerous solved and unsolved problems in each chapter Wide coverage of topics as per the latest syllabi of various universities

This Book Evolved Itself Out Of 25 Years Of Teaching Experience In The Subject, Moulding Different Important Aspects Into A One Year Course Of Mechanism And Machine Theory. Basic Principles Of Analysis And Synthesis Of Mechanisms With Lower And Higher Pairs Are Both Included Considering Both Kinematic And Kinetic Aspects. A Chapter On Hydrodynamic Lubrication Is Included In The Book. Balancing Machines Are Introduced In The Chapter On Balancing Of Rotating Parts. Mechanisms Used In Control Namely, Governors And Gyroscopes Are Discussed In A Separate Chapter. The Book Also Contains A Chapter On Principles Of Theory Of Vibrations As Applied To Machines. A Solution Manual To Problems Given At The End Of Each Chapter Is Also Available. Principles Of Balancing Of Linkages Is Also Included. Thus The Book Takes Into Account All Aspects Of Mechanism And Machine Theory To The Reader Studying A First Course On This Subject.This Book Is Intended For Undergraduate Students Taking Basic Courses In Mechanism And Machine Theory. The Practice Of Machines Has Been Initially To Use Inventions And Establishment Of Basic Working Models And Then Generalising The Theory And Hence The Earlier Books Emphasises These Principles. With The Advancement Of Theory Particularly In The Last Two Decades, New Books Come Up With A Stress On Specific Topics.The Book Retains All The Aspects Of Mechanism And Machine Theory In A Unified Manner As Far As Possible For A Two Semester Course At Undergraduate Level Without Recourse To Following Several Text Books And Derive The Benefits Of Basic Principles Recently Advanced In Mechanism And Machine Theory.

This book meets the requirements of undergraduate and postgraduate students pursuing courses in mechanical, production, electrical, metallurgical and aeronautical engineering. This self-contained text strikes a fine balance between conceptual clarity and practice problems, and focuses both on conventional graphical methods and emerging analytical approach in the treatment of subject matter. In keeping with technological advancement, the text gives detailed discussion on relatively recent areas of research such as function generation, path generation and mechanism synthesis using coupler curve, and number synthesis of kinematic chains. The text is fortified with fairly large number of solved examples and practice problems to further enhance the understanding of the otherwise complex concepts. Besides engineering students, those preparing for competitive examinations such as GATE and Indian Engineering Services (IES) will also find this book ideal for reference. KEY FEATURES  Exhaustive treatment given to topics including gear drive and cam follower combination, analytical method of motion and conversion phenomenon.  Simplified explanation of complex subject matter.  Examples and exercises for clearer understanding of the concepts.

"The subject Theory of Machines may be defined as that branch of Engineering-science, which deals with the study of relative motion between the various parts of a machine, and forces which act on them. The knowledge of this subject is very essential for an engineer in designing the various parts of a machine."

The concept of moving machine members during a thermodynamic cycle and the variation of displacements, velocities and accelerations forms the subject of kinematics.The study of forces that make the motion is the subject of kinetics; combining these two subjects leads to dynamics of machinery. When we include the machinery aspects such as links, kinematic chains, and mechanisms to form a given machine we have the subject of Theory of Machines. Usually this subject is introduced as a two-semester course, where kinematics and kinetics are taught simultaneously with thermodynamics or heat engines before progressing to the design of machine members. This book provides the material for first semester of a Theory of Machines- course. Th is book brings in the machine live onto the screen and explains the theory of machines concepts through animations and introduces how the problems are solved in industry to present a complete history in the shortest possible time rather than using graphical (or analytical) methods. Thus the students are introduced to the concepts through visual means which brings industrial applications by the end of the two semester program closer, and equips them better for design courses. The International Federation for promotion of Mechanism and Machine Science (IFToMM) has developed standard nomenclature and notation on Mechanism and Machine Science and this book adopts these standards so that any communication between scientists and in the classrooms across the world can make use of the same terminology. This book adopts HyperWorks MotionSolve to perform the analysis and visualizations, though the book can be used independent of the requirement of any particular software. However, having this software helps in further studies and analysis. The avis can be seen by entering the ISBN of this book at the Springer Extras website at extras.springer.com
