Book Description

The objective of this book is to provide the techniques
necessary to study the motion of machines. A focus is placed on
the application of kinematic theories to real-world machinery.
It is intended to bridge the gap between a theoretical study of
kinematics and the application to practical mechanisms.
Students completing a course of study using this book should
be able to determine the motion characteristics of a machine.
The topics presented in this book are critical in machine design
process as such analyses should be performed on design con-
cepts to optimize the motion of a machine arrangement.
This fourth edition incorporates much of the feedback
received from instructors and students who used the first three
editions. Some enhancements include a section introducing
special-purpose mechanisms; expanding the descriptions of
kinematic properties to more precisely define the property;
clearly identifying vector quantities through standard boldface
notation; including timing charts; presenting analytical
synthesis methods; clarifying the tables describing cam fol-
lower motion; and adding a standard table used for selection of
chain pitch. The end-of-chapter problems have been reviewed.
In addition, many new problems have been included.
It is expected that students using this book will have a
good background in technical drawing, college algebra, and
trigonometry. Concepts from elementary calculus are
mentioned, but a background in calculus is not required.
Also, knowledge of vectors, mechanics, and computer
application software, such as spreadsheets, will be useful.
However, these concepts are also introduced in the book.
The approach of applying theoretical developments to
practical problems is consistent with the philosophy of
engineering technology programs. This book is primarily
oriented toward mechanical- and manufacturing-related
engineering technology programs. It can be used in either
associate or baccalaureate degree programs.
Following are some distinctive features of this book:
1. Pictures and sketches of machinery that contain
mechanisms are incorporated throughout the text.
2. The focus is on the application of kinematic theories to
common and practical mechanisms.
3. Both graphical techniques and analytical methods are
used in the analysis of mechanisms.
4. An examination copy of Working Model®
, a commer-
cially available dynamic software package (see Section 2.3
on page 32 for ordering information), is extensively used
in this book. Tutorials and problems that utilize this
software are integrated into the book.
5. Suggestions for implementing the graphical techniques
on computer-aided design (CAD) systems are included
and illustrated throughout the book.
6. Every chapter concludes with at least one case study.
Each case illustrates a mechanism that is used on
industrial equipment and challenges the student to
discuss the rationale behind the design and suggest
improvements.
7. Both static and dynamic mechanism force analysis
methods are introduced.
8. Every major concept is followed by an example
problem to illustrate the application of the
concept.
9. Every Example Problem begins with an introduction
of a real machine that relies on the mechanism being
analyzed.
10. Numerous end-of-chapter problems are consistent
with the application approach of the text. Every
concept introduced in the chapter has at least one
associated problem. Most of these problems include
the machine that relies on the mechanism being
analyzed.
11. Where applicable, end-of-chapter problems are
provided that utilize the analytical methods and are
best suited for programmable devices (calculators,
spreadsheets, math software, etc.).
Initially, I developed this textbook after teaching mech-
anisms for several semesters and noticing that students did
not always see the practical applications of the material. To
this end, I have grown quite fond of the case study problems
and begin each class with one. The students refer to this as
the “mechanism of the day.” I find this to be an excellent
opportunity to focus attention on operating machinery.
Additionally, it promotes dialogue and creates a learning
community in the classroom.
Finally, the purpose of any textbook is to guide the
students through a learning experience in an effective
manner. I sincerely hope that this book will fulfill this inten-
tion. I welcome all suggestions and comments and can be
