En -standard handbook of machine design

Preface

books are directed primarily to the engineering student. Because of this, they contain

much theoretical material that is amenable to mathematical analysis. Such topics

are preferred by the instructor as well as the student because they appeal to the

student's scientific, mathematical, and computer backgrounds; are well-defined topics

with a beginning, a middle, and an end; and are easy to use in testing the student's

knowledge acquisition. The limited amount of time available for academic studies

severely limits the number of topics that can be used as well as their treatment. Since

textbooks devoted to mechanical design inevitably reflect this bias, there is great

need for a handbook that treats the universe of machine design—not just the readily

teachable part.

The beginning designer quickly learns that there is a great deal more to successful

design than is presented in textbooks or taught in technical schools or colleges.

This handbook connects formal education and the practice of design engineering by

including the general knowledge required by every machine designer.

Much of the practicing designer's daily informational needs are satisfied by various

pamphlets or brochures, such as those published by the various standards organizations.

Other sources include research papers, design magazines, and the various

corporate publications concerned with specific products. More often than not, however,

a visit to the design library or to the file cabinet will reveal that a specific publication

is on loan, lost, or out of date. This handbook is intended to serve such needs

quickly and immediately by giving the designer authoritative, up-to-date, understandable,

and informative answers to the hundreds of such questions that arise

every day in his or her work. Mathematical and statistical formulas and tabulations

are available in every design office and, for this reason, are not included in this handbook.
