After all, a good engineer knows that he or she must remain a student throughout their entire professional career. The continued tremendous growth of knowledge, including the areas of kinematics and dynamics of machinery, over the past 50 years has resulted in great pressure on the engineering curricula of many schools for the substitution of "modern" subjects for those perceived as weaker or outdated.
At some schools, depending on the faculty, this has meant that kinematics and dynamics of machines could only be made available as an elective topic for specialized study by a small number of students; at others it re- mained a required subject for all mechanical engineering students.
At other schools, it was required to take on more design emphasis at the expense of depth in analysis. In all, the times have produced a need for a textbook that satisfies the requirements of new and changing course structures. Much of the new knowledge developed over this period exists in a large variety of technical papers, each couched in its own singular language and lathe tools in delhi germany and each requiring additional background for its comprehension.
The individual contributions being published might be used to strengthen the engineering courses if first the neces- sary foundation were provided and a common notation and nomenclature were estab- lished. These lathe tools in delhi germany developments could then be integrated into existing courses so as to provide a logical, modern, and comprehensive whole. To provide the background that will allow such an integration is the purpose of this book.
To develop a broad and basic comprehension, all the methods of analysis and de- velopment lathe tools in delhi germany to the literature of the field are employed.
We have used graphical methods of analysis and synthesis extensively throughout the book because the authors are firmly of the opinion that graphical computation provides visual feedback that en- hances the student's understanding of the basic nature of and interplay between the equations involved. Therefore, in this book, graphic methods are presented as one pos- sible solution technique for vector equations defined by the fundamental laws of me- chanics, rather than as mysterious graphical "tricks" to be learned by rote and applied blindly.
In addition, although graphic techniques may be lacking in accuracy, they can be performed quickly and, even though inaccurate, sketches can often provide reason- able estimates of a solution or can be used to check the results of analytic or numeric so- lution techniques.
We also use conventional methods of vector analysis throughout the book, both in deriving and presenting the governing equations and in their solution.
In the chapters dealing with three-dimensional kinematics and robotics, we briefly present an introduction to Denavit and Hartenberg's methods using transformation matrices. With certain exceptions, we have endeavored to use U. Customary units and SI units in about equal proportions throughout the book. One of the dilemmas that all writers on the subject of this book have faced is how to distinguish between the motions of two different points of the same moving body and the motions of coincident points of two different moving bodies.
In other texts it has been customary to describe both of these as "relative motion"; but because they are two distinct situations and are described by different equations, this causes the student diffi- culty in distinguishing between them.
We believe that we have greatly relieved this problem by the introduction of the terms motion difference and apparent motion and two different notations for the two cases. Thus, for example, the book uses the two terms, velocity difference and apparent velocity, instead of the term "relative velocity," which will not be found when speaking rigorously. This approach is introduced beginning with the concepts of position and displacement, used extensively in the chapter on velocity, and brought to fulfillment in the chapter on accelerations where the Coriolis component always arises in, and only in, the apparent acceleration equation.
Another feature, new with the third edition, is the presentation of kinematic coeffi- cients, which are derivatives of various motion variables with respect to the input motion rather than with respect to tirr. The authors believe that these provide several new and important advantages, among which are the following: 1 They clarify for the student those parts of a motion problem which are kinematic geometric in their nature, and they clearly separate them from those that are dynamic or speed-dependent.
Access to personal computers and programmable calculators is now commonplace and is of considerable importance to the material of this book. Yet engineering educa- tors have told us very forcibly that they do not want computer programs included in the text. They prefer to write their own programs and they expect their students to do so too. Having programmed almost all the material in the book many times, we also understand that the book should not become obsolete with changes in computers or programming languages.
Part 1 of this book is an introduction that deals mostly with theory, with nomencla- ture, with notation, and with methods of analysis. Serving as an introduction, Chapter 1 also tells what a mechanism is, what a mechanism can do, how mechanisms can be clas- sified, and some of their limitations. Chapters 2, 3, and 4 are concerned totally with analysis, specifically with kinematic analysis, because they cover position, velocity, and acceleration analyses, respectively.
Part 2 of the book lathe tools in delhi germany on to show engineering applications involving the selection, the specification, the design, and the sizing of mechanisms to accomplish specific mo- tion objectives. This part includes lathe tools in delhi germany on cam lathe tools in delhi germany, gears, gear trains, synthesis of lathe tools in delhi germany, spatial mechanisms, and robotics.
Part 3 then adds the dynamics of machines. In a sense this is concerned with the consequences of the proposed mechanism design specifications. What forces are produced?
Are there any unexpected operating results? Will the proposed design be satisfactory in all respects? The third edition includes complete new chapters on the analysis and design of flywheels, governors, and gyroscopes. As with all topics and all texts, the subject matter of this book also has limits. Prob- ably the clearest boundary on the coverage in this text is that it is limited to the study of rigid-body mechanical systems.
It does study multibody systems with connections or constraints between them. However, all elastic effects are assumed to come within the connections; the shapes of the individual bodies are assumed constant. This assumption is necessary to allow the separate study of kinematic effects from those of dynamics. Because each individual body is assumed rigid, it can have no strain; therefore the study of stress is also outside of the scope of this text.
It is hoped, however, that courses lathe tools in delhi germany this text can provide background for the later study of stress, strength, fatigue life, modes of failure, lubrication, and other aspects important to the proper design of me- chanical systems. John J. Uicker, Jr. Gordon R.

He first wrote Kinematic Analysis of Mechanisms in and then wrote Dynamic Analysis of Machines in ], and these were published in a single volume titled Theory of Machines in ; these have evolved over the years to become the current text, Theory of Machines and Mechanisms, now in its third edition.
He was awarded the B. After severa] years in industry, he devoted his career to teaching, writing, and service to his profession starting first at Clemson University and later at the University of Michigan. His textbooks have been widely used throughout the United States and internationally.
The subject, and therefore this book, divides itself naturally into three parts. Part 1, which includes Chapters 1 through 4, is concerned with mechanisms and the kinematics of mechanisms, which is the analysis of their motions.
Part 1 lays the groundwork for Part 2, comprising Chapters 5 through 13, in which we study the methods of designing mechanisms. Finally, in Part 3, which includes Chapters 14 through 23, we take up the study lathe tools in delhi germany kinetics, the time-varying forces in machines and the resulting dynamic phenomena that must be considered in their design.
The design of a modern machine is often very complex. In the design of a new engine, for example, the automotive engineer must deal lathe tools in delhi germany many interrelated questions. What is the relationship between the motion of the piston and the motion of the crankshaft? What will be the sliding velocities and the loads at the lubricated surfaces, and what lubricants are available for the purpose?
