Book Description
This book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. This is the most advanced reference guide to the state of the art in gear engineering. Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined. The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears

Book Description
Written with honesty and humor, this is the engaging story of Tiff Needell's life around cars and motor racing. For nearly 25 years Tiff has been a well-known television personality, first on Top Gear – where he worked alongside Jeremy Clarkson – and then on Channel Five's Fifth Gear. Besides this, Tiff had an incredibly varied and long motor racing career that saw him reach the heights of a Grand Prix drive at Monaco and escape unharmed from a horrific 200mph crash at Le Mans.

Book Description
This book provides a compact history of gears, by summarizing the main stages of their development and the corresponding gradual acquisition of engineering expertise, from the antiquity to the Renaissance and the twentieth century. This brief history makes no claim to be exhaustive, since the topic is so extensive, complex and fascinating that it deserves an entire encyclopedia. Despite its brevity, the book debunks a number of popular misconceptions, such as the belief that the first literary description of a gear was supplied by Aristotle. It disproves not only this myth, but also other peremptory statements and/or axiomatic assumptions that have no basis in written documents, archaeological findings or other factual evidence. The book is chiefly intended for students and lecturers, historians of science and scientists, and all those who want to learn about the genesis and evolution of this topic.

Book Description
The fourth truth about the ways of the Pythagoreans and the followers of Pythagoras. Set throughout time with magic and technology, both are at their extremities. One has come full force while the other one is still thinking. Making way to a utopia, the two will become revealed in their own time. The Pythagoreans hold the key to survival. It is up to the element to lay out the endemic duel of adversities throughout the universe as we become privileged in the workings of Our Father, the Deity of mankind . . .

Book Description
In striving for optimal comfort and safety conditions in road vehicles, today’s electronically controlled components provide a range of new options. These are developed and tested using computer simulations in software in the loop or hardware in the loop environments—an advancement that requires the modern automotive engineer to be able to build basic simulation models, handle higher level models, and operate simulation tools effectively. Combining the fundamentals of vehicle dynamics with the basics of computer simulated modeling, Road Vehicle Dynamics: Fundamentals and Modeling Aspects draws on lecture notes from undergraduate and graduate courses given by the author, as well as industry seminars and symposiums, to provide practical insight on the subject. Requiring only a first course in dynamics and programming language as a prerequisite, this highly accessible book offers end-of-chapter exercises to reinforce concepts as well as programming examples and results using MATLAB®. The book uses SI-units throughout, and begins with an introduction and overview of units and quantities, terminology and definitions, multibody dynamics, and equations of motion. It then discusses the road, highlighting both deterministic and stochastic road models; tire handling including contact calculation, longitudinal and lateral forces, vertical axis torques, and measurement and modeling techniques; and drive train components and concepts such as transmission, clutch, and power source. Later chapters discuss suspension systems, including a dynamic model of rack-and-pinion steering as well as double-wishbone suspension systems; force elements such as springs, anti-roll bars, and hydro-mounts; and vehicle dynamics in vertical, longitudinal, and lateral directions using a simple model approach to examine the effects of nonlinear, dynamic, and active force elements. Highlighting useable knowledge, the book concludes with a three-dimensional vehicle model and typical results of standard driving maneuvers.

Book Description
For legions of soccer fans, the players on the U.S. Women's National Soccer Team are the game's standard-bearers. Together their accomplishments include four World Cup titles and four Olympic gold medals. Within five years of their inaugural match in 1985, the team was the best women's soccer team on the planet. But its rise was neither easy nor harmonious. The national team came onto the scene when team sports for women were in their infancy. The players were paid little and played to sparse crowds on marginal pitches and carried their own equipment and luggage. They faced discrimination and unequal treatment, most notably from their governing bodies, FIFA and U.S. Soccer. The Sisterhood is the story of the first and second generations of national team players, known as the 99ers, who were the driving force behind the rise of U.S. women's soccer and who built the foundation for the team's enduring success. Rob Goldman takes the reader onto the pitch and into the minds of the players and coaches for the team's greatest victories and most heartbreaking defeats. Among those featured are players Michelle Akers, Julie Foudy, Mia Hamm, and Brandi Chastain, as well as coaches Anson Dorrance and Tony DiCicco. When the team won the '99 World Cup in front of more than ninety thousand fans at the Rose Bowl, it was the largest crowd to ever attend a women's sporting event. After Brandi Chastain's winning penalty kick beat China, everything changed. These women's soccer players were no longer outcasts; they were hard-nosed players and leaders who not only transformed women's sports but led a cultural revolution. They were trailblazers, role models, and selfless best friends. Their story, told here largely in the voices of the players and coaches who were there, is epic and inspiring.
