Thorough in its coverage of basic theory, from the lever and inclined plane to internal combustion engines and power trains, it requires nothing more than an understanding of the most elementary mathematics. Beginning with the simplest of machines — the lever — the text proceeds to discussions of the block and tackle (pulleys and hoists), wheel and axle, the inclined plane and the wedge, the screw, and different types of gears (simple, spur, bevel, herringbone, spiral, worm, etc.). A chapter on the concept of work discusses the measurement of work, friction, and efficiency; this is followed by investigations of power, force, and pressure, with explanations of the uses of scales, balances, gauges, and barometers. The fundamentals of hydrostatic and hydraulic machines (such as the hydraulic braking system and the hydraulic press) are discussed in detail. The remaining chapters cover machine elements (bearings and springs), basic mechanisms (gear differential, couplings, cams, clutches), the internal combustion engine and power trains (including explanations of various transmission systems — synchromesh, auxiliary, etc.). Every concept is clearly defined, and discussions always build easily from elementary theory to specific applications familiar to anyone with the slightest interest in mechanics. Important concepts, machine components, and techniques are clearly illustrated in more than 200 diagrams, drawings, and cross-sections that reveal inner workings — all of these help to clarify even further an already clear and well-organized presentation. Although it was originally designed for use in U.S. Naval Training Schools, this book can be used to great advantage as a basic text in mechanical engineering in standard technical schools, and it will be immensely valuable even to lay readers who desire a basic knowledge of mechanics.

    He was a celebrity during the height of America’s Gilded Age. In this book, you will read about his friendship with Mark Twain, his furious competition with his former employer Thomas Edison, his uneasy relationship with billionaire J.P. Morgan, and his rivalry with Albert Einstein. During his lifetime, Tesla revolutionized the field of electrical engineering with his most famous invention: the induction motor. But that wasn’t all he contributed to the world of technology. His coils, turbines, robotic boats, and mysterious “death ray” continue to beguile the imagination and inspire the inventors of the 21st century. But who was Tesla really? This book will take you from his early childhood in Croatia, where he experienced strange optical visions and “luminous phenomenon” that gave him near super-human powers of memory and visualization, to the “War of the Currents”, Thomas Edison’s bizarre campaign to ruin Tesla’s reputation. From trying to fight the Spanish American War with robots, to electrifying the skies of the Colorado desert, and to starting an earthquake in the middle of New York city, learn how Nikola Tesla shaped the world we live in today.

    Tome was born in 1782 near present-day Harrisburg and lived on the upper Susquehanna for much of his life. He tells colorful (and mostly true) tales about his hunting exploits in the Pennsylvania wilderness, as he tracked elk, wolves, bears, panthers, foxes, and other large animals through the state’s north-central mountains, earning wide renown among his contemporaries. His stories contain suspenseful chase scenes, accidents, and narrow escapes, inviting the reader to view a still-wild Pennsylvania through the eyes of one who “was never conquered by man or animal.” Pioneer Life, originally published in 1854, has since been reprinted several times. This classic hunting memoir includes the following chapters: I. Birth and Early Life II. Hunting the Elk III. Capturing a Live Elk IV. Face of the Country V. Face of the Country — Continued VI. Danger From Rattlesnakes VII. Wolf and Bear Hunting VIII. Another Elk Hunt IX. Elk-Hunting on the Susquehannah X. Elk-Hunting — Continued XI. Nature, Habits, and Manner of Hunting the Elk XII. Elk and Bear Hunting in Winter XIII. Hunting on the Clarion River XIV. Hunting and Trapping XV. The Bear, Its Nature and Habits XVI. Hunting Deer at Different Seasons XVII. Nature and Habits of the Panther, Wolf and Fox XVIII. Rattlesnakes and Their Habits XIX. Distinguished Lumbermen, Etc. XX.. Reminiscences of Cornplanter XXI.

    But what should we change and how do we do it? Annabel Streets and Susan Saunders spent their 30s climbing the career ladder, having children and caring for elderly parents - all at the same time. By their 40s, they were exhausted, stressed, sleeping too little and rushing too much. They began to ask whether the prolonged ill health and dementia suffered by their parents was their inevitable future too - could they do anything to avoid requiring their own children to care for them in old age? Thus began THE AGE-WELL PROJECT. With incredible tenacity, Annabel and Susan read 50,000 scientific research papers on all aspects of ageing to find what advice cutting-edge research can offer us on how to ensure the longer lives we're living are healthy and happy. Putting their findings into practice, they found that the lifestyle changes they made were having incredible benefits on their health and wellbeing now - as well as for the future. Told with empathy and humour, in THE AGE-WELL PROJECT Annabel and Susan share the 50 key lessons they learned, the meals they cooked and the experts' tips they uncovered to make the second half of your life the best half of your life - happy, healthy and disease-free. Author BiographyAnnabel was a founder member of an award-winning marketing company, advising the chief executives of companies such as Sony, Reuters and the Financial Times.

    Amazing new tools, materials and skills turn us all into makers. Using technology to make, repair or customize the things we need brings engineering, design and computer science to the masses. Fortunately for educators, this maker movement overlaps with the natural inclinations of children and the power of learning by doing. The active learner is at the center of the learning process, amplifying the best traditions of progressive education. This book helps educators bring the exciting opportunities of the maker movement to every classroom. Children are natural tinkerersTheir seminal learning experiences come through direct experience with materials. Digital fabrication, such as 3D printing and physical computing, including Arduino, MaKey MaKey and Raspberry Pi, expands a child’s toy and toolboxes with new ways to make things and new things to make. For the first time ever, childhood inventions may be printed, programmed or imbued with interactivity. Recycled materials can be brought back to life. While school traditionally separates art and science, theory and practice, such divisions are artificial. The real world just doesn’t work that way! Architects are artists. Craftsmen deal in aesthetics, tradition and mathematical precision. Video game developers rely on computer science. Engineering and industrial design are inseparable. The finest scientists are often accomplished musicians. The maker community brings children, hobbyists and professionals together in a glorious celebration of personal expression with a modern flare. When 3-D printing, precision cutting, microcomputer control, robotics and computer programming become integral to the art studio, auto shop or physics lab, every student needs access to tools, knowledge and problem solving skills. The maker movement not only blurs the artificial boundaries between subject areas, it erases distinctions between art and science while most importantly obliterating the crippling practice of tracking students in academic pursuits or vocational training. There are now multiple pathways to learning what we have always taught and things to do that were unimaginable just a few years ago. Making for every classroom budgetEven if you don’t have access to expensive (but increasingly affordable) hardware, every classroom can become a makerspace where kids and teachers learn together through direct experience with an assortment of high and low-tech materials. The potential range, breadth, power, complexity and beauty of projects has never been greater thanks to the amazing new tools, materials, ingenuity and playfulness you will encounter in this book. In this practical guide, Sylvia Martinez and Gary Stager provide K-12 educators with the how, why, and cool stuff that supports classroom making.
