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.

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.

Computer aided design (CAD) emerged in the 1960s out of the growing acceptance of the use of the computer as a design tool for complex systems. As computers have become faster and less expensive while handling an increasing amount of information, their use in machine design has spread from large industrial needs to the small designer.

This book contains principles and practices for mechanical designers and represent engineering fundamentals in a practical way.

"Discusses the basic concepts: stresses involved and design procedures for simple machine elements"--

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.
