This book is intended to supply engineering professionals and students with a comprehensive and definitive reference to statics and dynamics of solids and structures. The book is for use as a resource and design tool in research and development, and for use as a study guide and learning aid in engineering education. The book is written to meet the needs for interactive computing in technical referencing and engineering education. These needs result from the design requirements for high-accuracy and high-performance structures, machines and devices in a variety of engineering applications, and from the trend of engineering curriculum development in response to today's environment of fast-changing technologies.
