This new, second edition of the 1944 classic serves as a crucial compilation of house rules, or a professional code. It addresses three areas: what the beginner needs to learn at once; laws relating chiefly to engineering executives; and purely personal considerations for engineers. Packed with contemporary examples, this new volume is a must for those entering the engineering field or those interested in improving their professional effectiveness. Key additions and changes have been included for today's engineers, and this edition is written in a style more familiar to today's readers.
