The Theory of Machines is an important subject to mechanical engineering students of both bachelor's and diploma level. One has to Understand The basics of kinematics and dynamics of machines before designing and manufacturing any component. The subject material is presented in such a way that an average student can easily Understand The concepts. The graphical methods of analysis are given preference over analytical wherever possible though they lack in accuracy but can be performed quickly. Particular care has been taken to draw diagrams to scale correctly. The results are compared with analytical ones wherever possible. Common doubts that the students have while preparing For The examinations or new faculty in the classrooms have been kept in mind. The same examples are being explained wherever different methods are there instead of giving different examples. The effect of the different parameters on the end result also is shown in the same problem, For example, In cams and governors etc. In the exercises at the end of each chapter, questions from the question papers of various universities are given under three categories - short answer questions, problems, multiple choice questions. Some of the questions may be seen repeated. One should note that they are being given repeatedly and are important for examination purpose.

Theory of Machines and Mechanisms, Third Edition, is a comprehensive study of rigid-body mechanical systems and provides background for continued study in stress, strength, fatigue, life, modes of failure, lubrication and other advanced aspects of the design of mechanical systems. This third edition provides the background, notation, and nomenclature essential for students to understand the various and independent technical approaches that exist in the field of mechanisms, kinematics, and dynamics of machines. The authors employ all methods of analysis and development, with balanced use of graphical and analytic methods. New material includes an introduction of kinematic coefficients, which clearly separates kinematic (geometric) effects from speed or dynamic dependence. At the suggestion of users, the authors have included no written computer programs, allowing professors and students to write their own and ensuring that the book does not become obsolete as computers and programming languages change. Part I introduces theory, nomenclature, notation, and methods of analysis. It describes all aspects of a mechanism (its nature, function, classification, and limitations) and covers kinematic analyses (position, velocity, and acceleration). Part II shows the engineering applications involved in the selection, specification, design, and sizing of mechanisms that accomplish specific motion objectives. It includes chapters on cam systems, gears, gear trains, synthesis of linkages, spatial mechanisms, and robotics. Part III presents the dynamics of machines and the consequences of the proposed mechanism design specifications. New dynamic devices whose functions cannot be explained or understood without dynamic analysis are included. This third edition incorporates entirely new chapters on the analysis and design of flywheels, governors, and gyroscopes.

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

MECHANISMS AND MACHINES: KINEMATICS, DYNAMICS, AND SYNTHESIS has been designed to serve as a core textbook for the mechanisms and machines course, targeting junior level mechanical engineering students. The book is written with the aim of providing a complete, yet concise, text that can be covered in a single-semester course. The primary goal of the text is to introduce students to the synthesis and analysis of planar mechanisms and machines, using a method well suited to computer programming, known as the Vector Loop Method. Author Michael Stanisic's approach of teaching synthesis first, and then going into analysis, will enable students to actually grasp the mathematics behind mechanism design. The book uses the vector loop method and kinematic coefficients throughout the text, and exhibits a seamless continuity in presentation that is a rare find in engineering texts. The multitude of examples in the book cover a large variety of problems and delineate an excellent problem solving methodology. Important Notice: Media content referenced within the product description or the product text may not be available in the ebook version.

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.
