Book Description :

Some background information is given together with the scope and objectives of a 5-year, Joint Winter Runway Friction Measurement Program between the National Aeronautics & Space Adminstration (NASA), Transport Canada (TC), and the Federal Aviation Administration (FAA). The primary objective of this effort is to perform instrumental aircraft and ground vehicle tests aimed at identifying a common number that all the different ground vehicle devices would report. This number, denoted the International Runway Friction Index (IRFI), will be related to all types of aircraft stopping performance. The range of test equipment, the test sites, test results and accomplishments, the extent of the substantial friction database compiled, and future test plans will be described. Several related studies have also been implemented including the effects of contaminant type on aircraft impingement drag, and the effectiveness of various runway and aircraft de-icing chemical types, and application rates.

Book Description :

Metal alloys were tested for sliding friction and wear characteristics in vacuum and in air. One purpose was the analysis of variations in the coefficient of friction with changes in air pressure, hardness, and type of alloy. Another purpose was the evolution of a scheme for description of wear patterns. With a Bowden-Tabor apparatus, sliders of various alloys were revolved in contact with a steel plate. Soft and hard steel, titanium, aluminum, copper, and copper-beryllium alloys were tested. Hardness of steel in the plate was varied. Visual and metallographic inspection, as well as study of microhardness traverses from below the wear interface, provided the results. Photomicrographs showing wear in the metal alloys are presented. This paper also provides graphical description of variations in the coefficient of friction. A description of observed wear patterns is accomplished by a scheme of four categories: prow formation, severe rider wear, intermediate rider wear, and mild rider wear. In each category, wear pattern is correlated with a mechanism responsible for its formation.

Book Description :

The effect of crystal and order-disorder transformations on friction and wear for Be-Co and FeCo alloys were studied in sliding friction experiments in vacuum at elevated temperatures. The results show that friction increases fourfold for the beryllium-cobalt alloy during transformation and that friction remains high until the reverse or cooling transformation occurs. The friction and wear of Be-Co are markedly superior to 440-C stainless steel. The order-disorder transformation in FeCo increases friction by a factor of 30 and also significantly increases wear. Increased sliding speed and loading affect the transformation. The friction behavior during heating is in good agreement with the type of order-temperature relation in FeCo.

Book Description :

Terrorism is an extreme form of radicalization. In this ground-breaking and important book, Clark McCauley and Sophia Moskalenko identify and outline twelve mechanisms of political radicalization that can move individuals, groups, and the masses to increased sympathy and support for political violence. Co-authored by two psychologists both acknowledged in their field as experts in radicalization and consultants to the Department of Homeland Security and other government agencies, Friction draws on wide-ranging case histories to show striking parallels between 1800s anti-czarist terrorism, 1970s anti-war terrorism, and 21st century jihadist terrorism. Altogether, the twelve mechanisms of political radicalization demonstrate how unexceptional people are moved to exceptional violence in the conflict between states and non-state challengers. In this revised and expanded edition, McCauley and Moskalenko use the twelve mechanisms to analyze recent cases of lone-wolf terrorists and illustrate how individuals can become radicalized to jihadist violence with group influence or organizational support. Additionally, in the context of the Islamic State's worldwide efforts to radicalize moderate Muslims for jihad, they advance a model that differentiates radicalization in opinion from radicalization in action, and suggest different strategies for countering these diverse forms of radicalization. As a result, the authors conclude that the same mechanisms are at work in radicalizing both terrorists and states targeted by terrorists, implying that these conclusions are as relevant for policy-makers and security officers as they are for citizens facing the threat of terror today.

Book Description :

A wheel turns because of its encounter with the surface of the road; spinning in the air it goes nowhere. Rubbing two sticks together produces heat and light; one stick alone is just a stick. In both cases, it is friction that produces movement, action, effect. Challenging the widespread view that globalization invariably signifies a "clash" of cultures, anthropologist Anna Tsing here develops friction in its place as a metaphor for the diverse and conflicting social interactions that make up our contemporary world. She focuses on one particular "zone of awkward engagement"--the rainforests of Indonesia--where in the 1980s and the 1990s capitalist interests increasingly reshaped the landscape not so much through corporate design as through awkward chains of legal and illegal entrepreneurs that wrested the land from previous claimants, creating resources for distant markets. In response, environmental movements arose to defend the rainforests and the communities of people who live in them. Not confined to a village, a province, or a nation, the social drama of the Indonesian rainforest includes local and national environmentalists, international science, North American investors, advocates for Brazilian rubber tappers, UN funding agencies, mountaineers, village elders, and urban students, among others--all combining in unpredictable, messy misunderstandings, but misunderstandings that sometimes work out. Providing a portfolio of methods to study global interconnections, Tsing shows how curious and creative cultural differences are in the grip of worldly encounter, and how much is overlooked in contemporary theories of the global.

Book Description :

It is one oft he major challenges for materials scientists and mechanical engineers to cope with the demands for long lasting and reliable systems in all markets and for all applications. The loss of energy by friction and the limits of endurance by wear can be countered by well selected materials and surfaces. The economical and ecological significance of wear and friction is undisputed and can equate to between 1 and 4% of the gross national products of industrial countries. Although the basic understanding of the mechanisms of friction and wear has drastically increased during the last five decades, many technical solutions are still carried out "following trial and error." Selection of the best material and the optimal topography in combination with the desired physical and chemical properties requires a systematic approach and a deep understanding of the acting mechanisms. Thus friction, wear, and wear protection are interdisciplinary fields which bring together scientists from the engineering, natural, biological and medical sciences. This book is an indispensable source for everybody who needs to solve the problems of friction and wear on materials.

Book Description :

This classic work, originally published in 1950, was a landmark in the development of the subject of tribology. When it was first published, one reviewer wrote that it 'marks the beginning of a new epoch in the study of friction and lubrication .... The most interesting and comprehensive work on a single branch of physics I have ever read.' For the 1986 reprint David Tabor wrote a new preface, reviewing developments in the subject in the 36 years since the book first appeared. He has also added an appreciation of the life and work of F.P. Bowden, who died in 1968.
