About this book
This extraordinary book explains the engine that has catapulted the Internet from backwater to ubiquity—and reveals that it is sputtering precisely because of its runaway success. With the unwitting help of its users, the generative Internet is on a path to a lockdown, ending its cycle of innovation—and facilitating unsettling new kinds of control. IPods, iPhones, Xboxes, and TiVos represent the first wave of Internet-centered products that can't be easily modified by anyone except their vendors or selected partners. These “tethered appliances” have already been used in remarkable but little-known ways: car GPS systems have been reconfigured at the demand of law enforcement to eavesdrop on the occupants at all times, and digital video recorders have been ordered to self-destruct thanks to a lawsuit against the manufacturer thousands of miles away. New Web 2.0 platforms like Google mash-ups and Facebook are rightly touted—but their applications can be similarly monitored and eliminated from a central source. As tethered appliances and applications eclipse the PC, the very nature of the Internet—its “generativity,” or innovative character—is at risk. The Internet's current trajectory is one of lost opportunity. Its salvation, Zittrain argues, lies in the hands of its millions of users. Drawing on generative technologies like Wikipedia that have so far survived their own successes, this book shows how to develop new technologies and social structures that allow users to work creatively and collaboratively, participate in solutions, and become true “netizens.”

About this book
This fully updated text provides the concepts, procedures, data, and analysis techniques needed to design and integrate machine elements into mechanical devices and systems. Focused on practical, safe, and efficient design, MACHINE ELEMENTS IN MECHANICAL DESIGN, 5/e emphasizes proven approaches and the use of readily available materials. Readers learn an integrated approach that considers the entire system while designing each element. The first six chapters guide students through the transition to design and expand on their understanding of designing for different loads. Next, the text thoroughly covers machine elements involved in power transmission equipment, from drives to rolling contact bearings. Finally, it covers many additional machine elements, including springs, electric motors, clutches, brakes, linear motion devices, and fasteers, plus issues associated with structural design, connections, and welding. Wherever practical, design equations, data, and procedures are specified. Problems offer realistic practice opportunities; throughout, the authors demonstrate the use of spreadsheets and included software to simplify complex procedures. Updated web links and references promote further exploration.
