Preface to An Introduction to Mechanical Engineering

In preparing this third edition, we have made many of the types of changes that one would expect: Sections have been rewritten and reorganized, new material has been added, some material has been removed.

New examples problems have been created, and small mistakes have been corrected. Almost 90 new homework problems have been developed and over 60 new figures have been included.

We have attempted to remain faithful to the philosophy of the first two editions by emphasizing the importance of the mechanical engineering profession to solving global problems, including new information

In Chapter  1 on recent professional trends, technology development, mechanical engineering career paths, and knowledge areas.

Also, in Chapter  1, we introduce an updated figure illustrating the organization of mechanical engineering topics both in this edition and in a typical mechanical engineering curriculum.

This figure is used in each chapter to depict graphically how the chapter’s content fi ts into the overall study of mechanical engineering.

A significant change in this edition is the shift of the chapter on Mechanical Design to Chapter 2, reflecting the growing importance of sound design principles in the development of engineered products and systems.

In Chapter 2, new material is included on design innovation, the National Academy of Engineering  Grand Challenges, design processes, customized production, and a case study on designing urban power infrastructures.

The following new material  has been integrated into the remaining chapters: technical problem solving, written and graphical communication, and significant figures (Chapter 3); Newton’s laws of motion.

(Chapter 4); sports technology (Chapter 6); updated notation and a solar power design example (Chapter 7). Each chapter example has been placed in an improved pedagogical format comprising the problem’s statement, approach, solution, and discussion.

In particular, the discussion portion is intended to highlight why the numerical answer is interesting or why it makes intuitive sense.

Symbolic equations are written alongside the numerical calculations. Throughout the textbook, the dimensions appearing in these calculations are explicitly manipulated and canceled in order to reinforce good technical problem-solving skills.

The “Focus on” boxes contain topical material, either conceptual or applied, that broadens the textbook’s coverage without detracting from its fl ow.

New topics in the “Focus on ” boxes include the dynamic field of mechanical engineering; product archaeology; engineering estimations using the Deep water Horizon disaster; ineffective communication practices.

The design of sustainable cities; advanced material technology; microfluidic devices; fluid flow across large surfaces; global energy consumption; renewable energy; design, policy, and innovation, nanomachines; and clean energy vehicles.

As was the intent with the first two editions, we have attempted to make the third edition’s content readily accessible to any student having a conventional secondary school background in mathematics and physics.

We have not relied on any mathematics beyond algebra, geometry, and trigonometry (which is reviewed in Appendix B), and in particular, we have not used any cross-products, integrals, derivatives, or differential equations.

Consistent with that view, we have intentionally not included a chapter that addresses the subjects of dynamics, dynamic systems, and mechanical vibration.

We remain focused on the earliest engineering students, many of whom will be studying calculus concurrently.

Keeping those students in mind, we feel that the added mathematical complexity would detract from this textbook’s overall mission.
