Mechanical Engineer’s Handbook – J. David Irwin, Dan B. Marghitu – 1st Edition


The Engineer’s Handbook was developed and written specifically to fill a need for and mechanical students. With over 1000 pages, 550 illustrations, and 26 tables the Mechanical Engineer’s Handbook is comprehensive, compact and durable.

The Handbook covers major areas of with succinct coverage of the definitions, formulas, examples, theory, proofs, and explanations of all principle subject areas. The Handbook is an essential, practical companion for all mechanical engineering students with core coverage of nearly all relevant courses included. Also, anyone preparing for the engineering licensing examinations will find this handbook to be an invaluable aid. Useful analytical techniques provide the student and practicing engineer with powerful for mechanical design.

This is designed to be a portable reference with a depth of coverage not found in “pocketbooks” of and definitions and without the verbosity, high price, and excessive size of the huge encyclopedic handbooks. If an engineer needs a quick reference for a wide array of information, yet does not have a full library of textbooks or does not want to spend the extra time and effort necessary to search and carry a six pound handbook, this book is for them.
