Award-winning archaeologists and New York Times and USA Today bestselling authors W. Michael Gear and Kathleen O'Neal Gear begin the stunning saga of the North American equivalent of ancient Rome in People of the Morning Star. The city of Cahokia, at its height, covered more than six square miles around what is now St. Louis and included structures more than ten stories high. Cahokian warriors and traders roamed from the Great Lakes to the Gulf of Mexico. What force on earth would motivate hundreds of thousands of people to pick up, move hundreds of miles, and once plopped down amidst a polyglot of strangers, build an incredible city? A religious miracle: the Cahokians believed that the divine hero Morning Star had been resurrected in the flesh. But not all is fine and stable in glorious Cahokia. To the astonishment of the ruling clan, an attempt is made on the living god's life. Now it is up to Morning Star's aunt, Matron Blue Heron, to keep it quiet until she can uncover the plot and bring the culprits to justice. If she fails, Cahokia will be torn asunder in warfare, rage, and blood as civil war consumes them all.

Chronicles the Beatles' use of instruments from 1956 through 1970, including photographs and discussion about Paul's 1963 Hofner 500/1 violin bass, John's Rickenbacker 325 12-string, and George's Gibson Les Paul.

Whether you're a first-time backpacker, an occasional weekend warrior, or a seasoned long-distance trekker, this guide is a must for any backpacking, hiking, or camping trip. Supreme long-distance hiker Andrew Skurka—accomplished adventure athlete, speaker, guide, and writer—shares his knowledge in this essential guide to backpacking gear and skills. Skurka recounts what he's learned from more than 30,000 miles of long-distance hikes, including the Appalachian, Pacific Crest, and Continental Divide Trails, and the 4,700-mile Alaska-Yukon Expedition. A show-and-tell guide to clothing, footwear, backpacks, shelter and sleep systems, camp stoves, and more, as well as tips on foot care, campsite selection, and hiking efficiency, this single book contains all the knowledge you'll need to hit the trail. This second edition features 16 new pages (including food on the trail and other essentials), and updates all gear recommendations.

Understanding how gears are formed and how they interact or ‘mesh’ with each other is essential when designing equipment that uses gears or gear trains. The way in which gear teeth are formed and how they mesh is determined by their geometry and kinematics, which is the topic of this book. Gears and Gear Drives provides the reader with comprehensive coverage of gears and gear drives. Spur, helical, bevel, worm and planetary gears are all covered, with consideration given to their classification, geometry, kinematics, accuracy control, load capacity and manufacturing. Cylindrical gear geometry is the basis for dealing with any gear drives, so this is covered in detail. Key features: Contains hundreds of 2D and 3D figures to illustrate all types of gears and gear drives, including planetary and worm gears Includes fundamental derivations and explanations of formulae Enables the reader to know how to carry out accuracy control and load capacity checks for any gear drive Includes directions for the practical design of gears and gear drives Covers DIN and ISO standards in the area Gears and Gear Drives is a comprehensive reference for gears and gear drive professionals and graduate students in mechanical engineering departments and covers everything important to know how to design, control and manufacture gear drives.

Provides an up-to-date, single-source reference for all aspects of the gear industry Presents an integrated approach to gear design and manufacture Includes new coverage of direct gear design and ready-to-use gear design Contains coverage of finite element analysis, gear vibration, load ratings, and gear failures

Advances in Gear Design and Manufacture deals with gears, gear transmissions, and advanced methods of gear production.The book is focused on discussion of the latest discoveries and accomplishments in gear design and production, with chapters written by international experts in the field. Topics are aligned to meet the requirements of the modern scientific theory of gearing, providing readers precise knowledge and recommendations on how perfect gears and gear transmissions can be designed and produced, and how they work. It explains how gears and gear transmissions can be designed to reach high a “power-to-weight” ratio, and how to design and produce compact, high-capacity gearboxes.

This book presents papers from the International Gear Conference 2014, held in Lyon, 26th-28th August 2014. Mechanical transmission components such as gears, rolling element bearings, CVTs, belts and chains are present in every industrial sector and over recent years, increasing competitive pressure and environmental concerns have provided an impetus for cleaner, more efficient and quieter units. Moreover, the emergence of relatively new applications such as wind turbines, hybrid transmissions and jet engines has led to even more severe constraints. The main objective of this conference is to provide a forum for the most recent advances, addressing the challenges in modern mechanical transmissions. The conference proceedings address all aspects of gear and power transmission technology and range of applications (aerospace, automotive, wind turbine, and others) including topical issues such as power losses and efficiency, gear vibrations and noise, lubrication, contact failures, tribo-dynamics and nano transmissions. - A truly international contribution with more than 120 papers from all over the world - A judicious balance between fundamental research and industrial concerns - Participation of the most respected international experts in the field of gearing - A wide range of applications in terms of size, power, speed, and industrial sector

To most mechanics a gear is a gear."A yellow primrose by the shore, A yellow primrose was, to him And it was nothing more;"And, in fact, the gear is often a gear and nothing more, sometimes barely that. But, if the mechanic will look beyond the tips of his fingers, he will find that it can be something more; that it is one of the most interesting objects in the field of science research, and not the simplest one; that it has received the attention of may celebrated mathematicians and engineers; and that the study of its features will not only add to his practical knowledge, but also to his entertainment. There is an element in mathematics, and in its near relative, theoretical mechanics, that possesses an educating and disciplining value beyond any capacity for earning present money. The thinking, inquisitive student of the day is the successful engineer or manufacturer of the future. The book is filled with wonderful turn of the century illustrations of gear wheels and gear cutting of every description.
