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.

"Should have broad appeal in many kinds of industry, ranging from automotive to computers—basically any organization concerned with products having moving parts!" —David A. Rigney, Materials Science and Engineering Department, Ohio State University, Columbus, USA In-Depth Coverage of Frictional Concepts Friction affects so many aspects of daily life that most take it for granted. Arguably, mankind’s attempt to control friction dates back to the invention of the wheel. Friction Science and Technology: From Concepts to Applications, Second Edition presents a broad, multidisciplinary overview of the constantly moving field of friction, spanning the history of friction studies to the evolution of measurement instruments. It reviews the gamut of friction test methods, ranging from simple inclined plans to sophisticated laboratory tribometers. The book starts with introductory concepts about friction and progressively delves into the more subtle fundamentals of surface contact, use of various lubricants, and specific applications such as brakes, piston rings, and machine components. Includes American Society of Testing and Management (ASTM) Standards This volume covers multiple facets of friction, with numerous interesting and unusual examples of friction-related technologies not found in other tribology books. These include: Friction in winter sports Friction of touch and human skin Friction of footware and biomaterials Friction drilling of metals Friction of tires and road surfaces Describing the tools of the trade for friction research, this edition enables engineers to purchase or build their own devices. It also discusses frictional behavior of a wide range of materials, coatings, and surface treatments, both traditional and advanced, such as thermally oxidized titanium alloys, nanocomposites, ultra-low friction films, laser-dimpled ceramics, and carbon composites. Even after centuries of study, friction continues to conceal its subtle origins, especially in practical engineering situations in which surfaces are exposed to complex and changing environments. Authored by a field specialist with more than 30 years of experience, this one-stop resource discusses all aspects of friction, from its humble beginnings to its broad application for modern engineers.

The “friction” of the title—one letter away from “fiction”—is what’s generated when reality and the imagination begin to rub against one another, and Eloy Urroz always makes sure that these two worlds are brought into uncomfortable proximity. This playful novel, told in the second person, is the story of an escalating series of comic events at a university,touched off when Matilde, “your” young wife, becomes determined to unravel the mystery surrounding the disappear- ance of a renowned politician. While she’s conducting a series of interviews with the vanished man’s lecherous son, a professor is watching, dazed, as his second marriage and academic career both collapse around him . . . and an army of fictional and historical characters begin to materialize in a certain imaginary Baja California town.

Sliding Friction

Author: Bo Persson
Publisher: Springer Science & Business Media
ISBN: 9783662036464
Release Date: 2013-03-14
Genre: Science

Sliding friction is one of the oldest problems in physics and certainly one of the most important from a practical point of view. The ability to produce durable low-friction surfaces and lubricant fluids has become an important factor in the miniaturization of moving components in many technological devices, e.g., magnetic storage, recording systems, miniature motors and many aerospace components. This book will be useful to physicists, chemists, materials scientists, and engineers who want to understand sliding friction. The book (or parts of it) could also form the basis for a modern undergraduate or graduate course on tribology.

Friction and Lubrication in Mechanical Design

Genre: Technology & Engineering

This book demonstrates how to control mechanisms of contact mechanics, heat generation and transfer, friction, noise generation, lubrication, and surface damage due to mechanical and thermal variables. Friction and Lubrication in Mechanical Design reviews various classical and new tribology problems beginning with history and ending with numerical optimization and examples, simplifies access to information for predicting and preventing friction and wear, and provides a useful tool for everyone involved in mechanical design, or in machinery monitoring.

Fundamentals of Friction

Author: I.L. Singer
Publisher: Springer Science & Business Media
ISBN: 0792319125
Release Date: 1992-08-31
Genre: Science

Fundamentals of Friction, unlike many books on tribology, is devoted to one specific topic: friction. After introductory chapters on scientific and engineering perspectives, the next section contains the necessary background within the areas of contact mechanics, surfaces and adhesion. Then on to fracture, deformation and interface shear, from the macroscopic behavior of materials in frictional contact to microscopic models of uniform and granular interfaces. Lubrication by solids, liquids and gases is presented next, from classical flow properties to the reorganization of monolayers of molecules under normal and shear stresses. A section on new approaches at the nano- and atomic scales covers the physics and chemistry of interfaces, an array of visually exciting simulations, using molecular dynamics, of solids and liquids in sliding contact, and related AFM/STM studies. Following a section on machines and measurements, the final chapter discusses future issues in friction.

Control of Machines with Friction

Release Date: 1991-01-31
Genre: Technology & Engineering

It is my ambition in writing this book to bring tribology to the study of control of machines with friction. Tribology, from the greek for study of rubbing, is the discipline that concerns itself with friction, wear and lubrication. Tribology spans a great range of disciplines, from surface physics to lubrication chemistry and engineering, and comprises investigators in diverse specialities. The English language tribology literature now grows at a rate of some 700 articles per year. But for all of this activity, in the three years that I have been concerned with the control of machines with friction, I have but once met a fellow controls engineer who was aware that the field existed, this including many who were concerned with friction. In this vein I must confess that, before undertaking these investigations, I too was unaware that an active discipline of friction existed. The experience stands out as a mark of the specialization of our time. Within tribology, experimental and theoretical understanding of friction in lubricated machines is well developed. The controls engineer's interest is in dynamics, which is not the central interest of the tribologist. The tribologist is more often concerned with wear, with respect to which there has been enormous progress - witness the many mechanisms which we buy today that are lubricated once only, and that at the factory. Though a secondary interest, frictional dynamics are note forgotten by tribology.

Genre: Juvenile Fiction

This stunning novel by E.R. Frank explores what happens when the truth is worse than the rumor. Twelve-year-old Alex loves her small alternative school. She hangs out with her best friend, Tim, every day, and Simon is the coolest teacher—he’s even starting a soccer team just for them. And then Stacey comes to town. With her tongue ring and air of confidence, Stacey immediately shakes things up in the classroom. Alex is drawn to her at first, but when Stacey starts rumors that something is going on between Alex and Simon, trouble brews. As the class and Tim begin to believe Stacey’s rumors, Alex starts to doubt what is really true herself. This explosive tale about school politics, relationships, and the frictional power of suggestion is “sure to spark heated discussions” (SLJ, starred review).
