While golf has a popular following among casual fans, it has become popular among another passionate yet unlikely group: scientists. Beyond the caddies, carts, and clubs, the game of golf is an applied science. The seemingly simple act of striking a golf ball invokes a wide range of processes, including physics principles such as energy transfer, kinetics, launch angles, spin, and momentum. However, in spite of the growing interest in the fledgling field of "golf science," few books thus far have provided a comprehensive introduction of the subject. In The Science of the Perfect Swing, mechanical engineer Peter Dewhurst offers a full treatment of the science of modern golf. Based on three decades of experience in the physics of golf, Dewhurst examines topics such as the interaction between club face and ball, various aspects of trajectory and impact, and the physics of putting. Rich in illustrations, graphs, and charts, Dewhurst presents physics-based discussions in an accessible format. Each chapter also contains a substantial "Findings and Consequences" section, which draws conclusions based on the science, and makes recommendations on ball-striking and other facets of the game. From the mechanics of club design to modeling the trajectory of the ball once it leaves the club face, The Science of the Perfect Swing unravels some of the elusive mysteries about what it takes to play a great game of golf. Interesting and informative, The Science of the Perfect Swing strikes a perfect balance between hard science and an accessible tone that will appeal to golf enthusiasts, engineers, and general readers of sports science.

The Science of the Perfect Swing appeals to those who are seeking a clear explanation of the inner workings of golf. It allows golfers to visualize the underlying physics of their sport, and so enjoy a deeper appreciation of good shot making. With numerous charts, tables, and drawings, Peter Dewhurst walks the reader through every scientific aspect of the game--including factors that many readers aren''t even aware affect their game at all! Each chapter is concerned with the findings and consequences of the science on actual shot making; rather than with the science itself. The science is relegated to the back of each chapter as optional reading. The intention of the work is to foster improved technique in the light of a broader fundamental understanding of the game. The majority of case studies in the book are taken from PGA and LPGA Tour players. With this engaging treatment of the science of golf, the seeming impossibility of the achievements of the world''s best players becomes all the more incredible. To drive a tiny ball hundreds of yards using a selection of equipment, to loft it over and around obstacles, to stop it on a green that it impacts at high speed, and then roll it over slopes and surface imperfections into a hole which can seem barely bigger than the golf ball itself, seems to defy, rather than illustrate, the laws of physics! Perhaps because of this, golf has remained wildly, and widely, popular for the last half-millennium. Peter Dewhurst helps clear up any confusion about the fundamentals of golf by examining all of the details from the one-second generation of speed in the swing, to the 0.0005-second explosive transfer of energy into the ball, through the dimple-powered flight, to the final elements of finesse leading to capture in the hole. Dewhurst combines expertise, from decades of award-winning engineering research and effective teaching, to make his writing engaging and educational for all readers.

Hailed as a groundbreaking and important textbook upon its initial publication, the latest iteration of Product Design for Manufacture and Assembly does not rest on those laurels. In addition to the expected updating of data in all chapters, this third edition has been revised to provide a top-notch textbook for university-level courses in product design and manufacturing design. The authors have added a comprehensive set of problems and student assignments to each chapter, making the new edition substantially more useful.See what’s in the Third Edition: Updated case studies on the application of DFMA techniquesExtended versions of the classification schemes of the features of products that influence the difficulty of handling and insertion for manual, high-speed automatic, and robot assembly Discussions of changes in the industry such as increased emphasis on the use of surface mount devicesNew data on basic manufacturing processesCoverage of powder injection moldingRecognized as international experts on the re-engineering of electro-mechanical products, the methods and guidelines developed by Boothroyd, Dewhurst, and Knight have been documented to provide significant savings in the product development process. Often attributed with creating a revolution in product design, the authors have been working in product design manufacture and assembly for more than 25 years. Based on theory yet highly practical, their text defines the factors that influence the ease of assembly and manufacture of products for a wide range of the basic processes used in industry. It demonstrates how to develop competitive products that are simpler in configuration and easier to manufacture with reduced overall costs.
