INTRODUCTION TO ENGINEERING DESIGN: Book 9, 7th Edition
ENGINEERING SKILLS AND HOVERCRAFT MISSIONS
This book is the seventh edition of the ninth textbook in this series dealing with Introduction to Engineering Design. Jim Dally, working with College House Enterprises and faculty members in the Clark School of Engineering, has prepared eight previous books in this series—a new one almost every academic year or two—for the first-year engineering students of the University of Maryland at College Park. Several other Colleges of Engineering have adopted one or more of the books in this series to introduce design and engineering skills for their first or second year students. The design, build and testing of a hovercraft model, described in Book 9, is such an interesting and challenging project that this is the seventh year we have used it (twelve previous semesters) with approximately 7,000 students. The project is also assigned for the first year Introduction to Engineering Design at the University of Nevada @ Reno, where it is in its sixth year and at the University of California at Irvine, where was used for two years.
The textbook is used to support the students during a semester-long project. Some of the material may be covered in lecture, recitation or in a computer laboratory or a model shop. Additional material is covered with reading assignments. In other instances, the students use the text as a reference document for independent study. Exercises, provided at the end of each chapter, may be used for assignments when the demands of the project on the students’ time are not excessive.
The book contains 17 chapters to present the many topics that first year engineering students should understand as they proceed through a significant portion of the product realization process. Product and system development processes is introduced in early in the text. An Introduction to the course and to the textbook is provided in Chapter 1 to alert the students to the demands of the course and to introduce them to the problems frequently encountered by other students in designing, building and testing a model of a hovercraft. Information on team skills and the importance of product development is covered in Chapters 2 and 3. Several hovercraft missions are also presented in Chapter 3, together with a description of the design concepts involved in hovercraft development. By assigning a demanding project, a holistic approach is employed in the student’s first engineering experience that is motivating. Design of a hovercraft enables instructors with an opportunity to integrate a wide spectrum of knowledge about many engineering topics. The student’s hands-on participation in a design, building, testing and competing in a hovercraft mission significantly enhances their learning process.
The theoretical background on fluid mechanics, needed to conduct elementary design analyses for the hovercraft, is presented in Chapter 4. Chapter 5 describes basic electric circuits, and batteries to provide technical background helpful for the design and control of the hovercraft. Many different sensors, used to aid in navigating the hovercraft, are introduced in Chapter 6. Concepts of statics and dynamics are introduced in Chapter 7 to enable the students to understand the forces and moments and their effect on controlling the motion of their hovercraft. Finally, an introduction to programming the Arduino microprocessor in a version of C is included in Chapter 8.
Two chapters on engineering graphics are included. In Chapter 9 the basic rules used in preparing engineering drawings are covered in detail. The use of tables and graphs in communicating engineering information using Microsoft Excel is presented in Chapter 10. The very important topic of communications is covered in two chapters. Chapter 11, on technical reports, describes many aspects of technical writing and library research. The most important lesson here is that a technical report is different than a term paper for the History or English Departments. An effective professional report is written for a predefined audience with specific objectives. The technical writing process is described, and many suggestions to facilitate composing, revision, editing and proofreading are given. Design briefings, covered in Chapter 12, shows the distinction among speeches, presentations and group discussions. Emphasis is placed on the technical presentation and the importance of preparing excellent visual aids. PowerPoint slides are usually employed as visual aids in a design briefing.
An introduction to the engineering profession, described in Chapter 13, covers engineering disciplines, on-the-job activities, salary statistics and registration information for your PE license. A useful student survival guide is given in Chapter 14. Three chapters dealing with engineering and society are included. A historical perspective on the role engineering played in developing civilization and on improving the lives of the masses is presented in Chapter 15. In this chapter, we move from the past into the present and indicate the current relationship between business, consumers and society. The twenty greatest engineering achievements of the 20th century are briefly described. Chapter 16 discusses the balance between safety and performance. Methods to evaluate and recognize risky environments are discussed. The chapter includes a listing of hazards, which is important in identifying the many different ways users of a product can be injured. Chapter 17 on ethics, character and engineering includes a large number of topics so the instructor can select from among them. A description of the Challenger and Columbia accidents are described in considerable detail, because both of these fatal crashes provide excellent case histories covering safety related conflicts between management and engineers.
