The fourth edition of A Guide to Writing as an Engineer updates Beer and McMurrey's popular book on communication and technical writing for engineers. Used predominantly in freshmen engineering survey courses, the text is also applicable for specific courses on engineering writing or technical communication later in the curriculum. A Guide to Writing as an Engineer deals with a variety of topics ranging from important writing concepts that apply to professional engineers, to content, organization, format and style of various kinds of engineering writing. The book also covers oral presentations, research techniques, ethics, and proper citation methods. Beer remains a practical, handy book that can function not only as a classroom textbook, but also as a reference and guide for writing and research, for practicing engineers.
