Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Origin of Quenching Cracks During the investigation of the dimensional changes which tool steel undergoes on hardening, it was found that a 1-inch diameter cylinder was very susceptible to cracking when quenched in oil but not when quenched in water. Presumably the stresses produced by the faster quenching (the latter case) are greater than in the former, so evidence of the cause of failure under low stress and not under high was sought. Examination of the cracked specimens showed that failure was due to tensional stress at the surface. The axial stress at the surface after quenching in water was found by experiment to be compressional and high. It was concluded therefrom that hardened steel, like glass, is highly resistant to compressional stress but not to tensional stress. Conditions producing cracks In a particular Oil-hardening steel were determined experimentally. The Observations recorded show cracks are 'produced by permanent stress, which reaches a maximum value at ordinary temperatures. Permanent tensional stress can be produced at the surface by cooling only when the coefficient of expansion. Is negative and the steel is plastic. This condition was demonstrated from an experimental study Of the expansion Of steel during hardening. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book The Handley Page Victor The History Development of a Classic Jet written by Roger Brooks and published by Pen and Sword. This book was released on 2006-09-21 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handley Page Victor was the longest serving V-Bomber with the RAF. It was conceived in 1945 and after much research and development the Mk 1 entered service in the late 1950s to become part of the UK's nuclear deterrent force. It could fly faster, higher and further than any comparable aircraft of that era. It boasted a unique crescent wing shape and was the most handsome of the three types of V bomber. It was later extensively modified to become the RAF's main tanker aircraft for in-flight refuelling and served in that role from 1965 until 1993. This is the most authoritative reference to the aircraft yet to be published. Commencing with the first design trials and test flights, each chapter includes personnel recollections from pilots and design staff, and is solidly based on official government and company reports, many of which are included. The text explains the introduction and operation once it was in RAF service and explains the various roles that it undertook and the many experiments and trials that took place to perfect the various systems required for these roles. The Mk 2 was a much improved model and many were adapted for tanker duties. All is fully explained with copious diagrams and rarely seen photographs. Lengthy appendices detail Aircraft Accident Reports and other unique information that has never been published.This is the ultimate reference book on this famous and much-loved aircraft.7 Colour Profiles by David Windle, 22 Colour Photographs, 170 Mono Photographs and 66 Diagrams
Download or read book Metallography and Microstructure in Ancient and Historic Metals written by David A. Scott and published by Getty Publications. This book was released on 1992-01-02 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: David A. Scott provides a detailed introduction to the structure and morphology of ancient and historic metallic materials. Much of the scientific research on this important topic has been inaccessible, scattered throughout the international literature, or unpublished; this volume, although not exhaustive in its coverage, fills an important need by assembling much of this information in a single source. Jointly published by the GCI and the J. Paul Getty Museum, the book deals with many practical matters relating to the mounting, preparation, etching, polishing, and microscopy of metallic samples and includes an account of the way in which phase diagrams can be used to assist in structural interpretation. The text is supplemented by an extensive number of microstructural studies carried out in the laboratory on ancient and historic metals. The student beginning the study of metallic materials and the conservation scientist who wishes to carry out structural studies of metallic objects of art will find this publication quite useful.

Download or read book Ignition written by John Drury Clark and published by Rutgers University Press. This book was released on 2018-05-23 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newly reissued debut book in the Rutgers University Press Classics Imprint is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise which eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, and described as “a good book on rocket stuff…that’s a really fun one” by SpaceX founder Elon Musk, readers will want to get their hands on this influential classic, available for the first time in decades.

Available in PDF, EPUB and Kindle. Book excerpt: In this ambitious successor to The Great Derangement, acclaimed writer Amitav Ghosh finds the origins of our contemporary climate crisis in Western colonialism’s violent exploitation of human life and the natural environment. A powerful work of history, essay, testimony, and polemic, Amitav Ghosh’s new book traces our contemporary planetary crisis back to the discovery of the New World and the sea route to the Indian Ocean. The Nutmeg’s Curse argues that the dynamics of climate change today are rooted in a centuries-old geopolitical order constructed by Western colonialism. At the center of Ghosh’s narrative is the now-ubiquitous spice nutmeg. The history of the nutmeg is one of conquest and exploitation—of both human life and the natural environment. In Ghosh’s hands, the story of the nutmeg becomes a parable for our environmental crisis, revealing the ways human history has always been entangled with earthly materials such as spices, tea, sugarcane, opium, and fossil fuels. Our crisis, he shows, is ultimately the result of a mechanistic view of the earth, where nature exists only as a resource for humans to use for our own ends, rather than a force of its own, full of agency and meaning. Writing against the backdrop of the global pandemic and the Black Lives Matter protests, Ghosh frames these historical stories in a way that connects our shared colonial histories with the deep inequality we see around us today. By interweaving discussions on everything from the global history of the oil trade to the migrant crisis and the animist spirituality of Indigenous communities around the world, The Nutmeg’s Curse offers a sharp critique of Western society and speaks to the profoundly remarkable ways in which human history is shaped by non-human forces.
