This book is a comprehensive engineering exploration of all the aspects of precision machine design—both component and system design considerations for precision machines. It addresses both theoretical analysis and practical implementation providing many real-world design case studies as well as numerous examples of existing components and their characteristics. Fast becoming a classic, this book includes examples of analysis techniques, along with the philosophy of the solution method. It explores the physics of errors in machines and how such knowledge can be used to build an error budget for a machine, how error budgets can be used to design more accurate machines.

The academic course of Machine Design Elements and Assemblies (a.k.a. "Machine Design," "Mechanical Engineering Design," etc.) is based on the fundamentals of several different core disciplines, and should prepare students to meet challenges associated with solving real-life mechanical engineering design problems commonly found in industry. Other works focus primarily on verifying calculations of existing machine elements in isolation, while this textbook goes beyond and includes the design calculations necessary for determining the specifications of elements for new assemblies, and accounting for the interaction between them. Machine Design Elements and Assemblies addresses the design considerations associated with the functionality of a full assembly. Most chapters end with a design project that gets progressively more complex. Numerous reviews of prerequisite materials are purposely not included in this title, resulting in a more concise, more practical, and far less expensive product for students, engineers, and professors. Rounding out this incredible package are 120 problems and answers that can be assigned as homework. And nearly 400 additional problems are available on the book's affiliated website, www.machinedesignea.com.

The latest ideas in machine analysis and design have led to a major revision of the field's leading handbook. New chapters cover ergonomics, safety, and computer-aided design, with revised information on numerical methods, belt devices, statistics, standards, and codes and regulations. Key features include: *new material on ergonomics, safety, and computer-aided design; *practical reference data that helps machines designers solve common problems--with a minimum of theory. *current CAS/CAM applications, other machine computational aids, and robotic applications in machine design. This definitive machine design handbook for product designers, project engineers, design engineers, and manufacturing engineers covers every aspect of machine construction and operations. Voluminous and heavily illustrated, it discusses standards, codes and regulations; wear; solid materials, seals; flywheels; power screws; threaded fasteners; springs; lubrication; gaskets; coupling; belt drive; gears; shafting; vibration and control; linkage; and corrosion.

In one complete volume, this essential reference presents an in-depth overview of the theoretical principles and techniques of electrical machine design. This timely new edition offers up-to-date theory and guidelines for the design of electrical machines, taking into account recent advances in permanent magnet machines as well as synchronous reluctance machines. New coverage includes: Brand new material on the ecological impact of the motors, covering the eco-design principles of rotating electrical machines An expanded section on the design of permanent magnet synchronous machines, now reporting on the design of tooth-coil, high-torque permanent magnet machines and their properties Large updates and new material on synchronous reluctance machines, air-gap inductance, losses in and resistivity of permanent magnets (PM), operating point of loaded PM circuit, PM machine design, and minimizing the losses in electrical machines> End-of-chapter exercises and new direct design examples with methods and solutions to real design problems> A supplementary website hosts two machine design examples created with MATHCAD: rotor surface magnet permanent magnet machine and squirrel cage induction machine calculations. Also a MATLAB code for optimizing the design of an induction motor is provided Outlining a step-by-step sequence of machine design, this book enables electrical machine designers to design rotating electrical machines. With a thorough treatment of all existing and emerging technologies in the field, it is a useful manual for professionals working in the diagnosis of electrical machines and drives. A rigorous introduction to the theoretical principles and techniques makes the book invaluable to senior electrical engineering students, postgraduates, researchers and university lecturers involved in electrical drives technology and electromechanical energy conversion.

This comprehensive text on principles and practice of mechanical design discusses the concepts, procedures, data, tools, and analytical methodologies needed to perform design calculations for the most frequently encountered mechanical elements such as shafts, gears, belt, rope and chain drives, bearings, springs, joints, couplings, brakes and clutches, flywheels, as well as design calculations of various IC engine parts. The book focuses on all aspects of design of machine elements including material selection and life or performance estimation under static, fatigue, impact and creep loading conditions. The book also introduces various engineering analysis tools such as MATLAB, AutoCAD, and Finite Element Methods with a view to optimizing the design. It also explains the fracture mechanics based design concept with many practical examples. Pedagogically strong, the book features an abundance of worked-out examples, case studies, chapter-end summaries, review questions as well as multiple choice questions which are all well designed to sharpen the learning and design skills of the students. This textbook is designed to appropriately serve the needs of undergraduate and postgraduate students of mechanical engineering, agricultural engineering, and production and industrial engineering for a complete course in Machine Design (Papers I and II), fully conforming to the prescribed syllabi of all universities and institutes.

New ways to design spaces for online interaction—and how they will change society. Computers were first conceived as “thinking machines,” but in the twenty-first century they have become social machines, online places where people meet friends, play games, and collaborate on projects. In this book, Judith Donath argues persuasively that for social media to become truly sociable media, we must design interfaces that reflect how we understand and respond to the social world. People and their actions are still harder to perceive online than face to face: interfaces are clunky, and we have less sense of other people's character and intentions, where they congregate, and what they do. Donath presents new approaches to creating interfaces for social interaction. She addresses such topics as visualizing social landscapes, conversations, and networks; depicting identity with knowledge markers and interaction history; delineating public and private space; and bringing the online world's open sociability into the physical world. Donath asks fundamental questions about how we want to live online and offers thought-provoking designs that explore radically new ways of interacting and communicating.
