applied strength of materials sixth edition pdf

Objectives of the Book

Applied Strength of Materials, Sixth Edition, provides comprehensive coverage of the
important topics in strength of materials with an emphasis on applications, problem solving, and design of structural members, mechanical devices, and systems. The book is written for the student in a course called Strength of Materials, Mechanics of Materials, or Solid Mechanics in an engineering technology program at the baccalaureate or associate degree level or in an applied engineering program.

This book provides good readability for the student, appropriate coverage of the principles of strength of materials for the faculty member teaching the subject, and a problemsolving and design approach that is useful for the practicing designer or engineer. Educational
programs in the mechanical, civil, construction, architectural, industrial, and manufacturing
fields will find the book suitable for an introductory course in strength of materials.


This text emphasizes the applications of the principles of strength of materials to mechanical, manufacturing, structural, and construction problems while providing a firm understanding of those principles. At the same time, the limitations on the use of analysis techniques are emphasized to ensure that they are applied properly. Both analysis and design approaches are used in the book.  

Units are a mixture of SI metric and U.S. Customary units, in keeping with the dual
usage evident in U.S. industry and construction. Where SI metric units are used, all data
for the problem are in appropriate metric units, including the section properties for numerous types and sizes of structural members in the Appendix. For metric problems, appendix
data now include actual commercially available metric components, with the actual SI
designations, and are not just U.S.-based components with the values soft converted.


Students should be able to apply the principles of statics prior to using this book. For
review, there is a summary in Chapter 1 of the main techniques from a course in Statics,
emphasizing the analysis of forces and moments. Several example problems are included
that use the principles of statics to solve practice problems in this book.

While not essential, it is recommended that students have completed an introductory
course in calculus. As called for by accrediting agencies, calculus is used to develop the
key principles and formulas used in this book. The application of the formulas and most
problem-solving and design techniques can be accomplished without the use of calculus.

Features of the Book

The Big Picture. Students should see the relevance of the material they study. They
should be able to visualize where devices and systems that they are familiar with depend
on the principles of strength of materials. For this reason, each chapter starts with a section
called The Big Picture. Here, the basic concepts developed in the chapter are identified and
students are asked to think about examples from their own experience where these concepts are used. A new, full color photograph is included in a special color image section for the Big Picture section for each chapter with an introduction that describes the relationship between the picture and the principles to be learned in that chapter. Sometimes students are asked to explore new things on their own to discover how a product works or how it can fail. They are coached to make observations about the behavior of common mechanical devices, vehicles, industrial machinery, consumer products, and structures. Educational philosophy indicates that students learn better and retain more when such methods are employed.

Activity-Based Learning.

Activity-based learning methods are integrated into the popular Big Picture section, a successful feature in all previous editions. The activity can be used independently by the students, by the instructor as a classroom demonstration, or a combination of these approaches. These activities allow the instructor and the students to extend the Big Picture dialog into hands-on experiences that give an enhanced appreciation and greater physical feel for the phenomena involved. Activities can help students from different disciplines work together and learn from each other.

The activities are generally simple and can be completed in a short amount of time with inexpensive materials and quick setups. The emphasis is on qualitative appreciation of the physical phenomena
with a modest amount of measurement involved. Educational research has shown that students learn better when they are personally involved in activities as opposed to listening to
lectures. Furthermore, retention of abilities learned is improved along with greater ability
to transfer learning to new and different applications.

Design Approaches.

This text provides extensive information about guidelines for design of mechanical devices and structural members, more than in most books on thissubject. The design approaches are based on another book by Professor Mott, Machine Elements in Mechanical Design, Fifth Edition, 2014, from Pearson/Prentice Hall. Learning about design in addition to analysis increases the usefulness of the book to students and professional users. There are some students who will not go on to a s bsequent course thatemphasizes design. They should get some introduction to the principles of design in the introductory course in strength of materials. For those who do proceed to a design course, they should enter that course with a higher level of design knowledge and capability.
