This text introduces students to the engineering profession, discussing factors such as the importance of engineering in developing a better society, the history of technological change, the ethical problems encountered in the profession, and future challenges facing engineers. Discussions of the various fields of engineering and career possibilities are featured and sample design problems are presented to introduce students to problem-solving methodologies required of engineers. The techniques of analysis and design are emphasized through elementary problems in a variety of engineering fields. A unique focus on engineers as integral to the development of our technological society sets this book apart from others in the field. The second edition features a separate chapter on the design process, remarks from engineers, an appendix on algebraic problem solving, and coverage of models, industrial practice, and concurrent engineering.
