Formulas.—Most formulas in engineering handbooks are given without showing how they have been derived or originated, because engineers and designers usually want only the final results; moreover, such derivations would require considerable additional space, and they belong in textbooks rather than in handbooks, which are primarily works of reference Although Machinery’s Handbook contains thousands of standard... special formulas, it is apparent that no handbook can include every kind of formula, because a great many formulas apply only to local designing or manufacturing problems Such special formulas are derived by engineers and designers for their own use The exact Copyright 2008, Industrial Press Inc., New York, NY - www.industrialpress.com Machinery's Handbook Guide 28th Edition 16 FORMULAS methods of... in pounds, given on Handbook 28 CD page 3259: W = 54 ,000D 2 This particular formula contains the constant 54,000, which was established by tests, and the formula is used to obtain the breaking load of wrought-iron crane chains to which a factor of safety of 3, 4, or 5 is then applied to obtain the working load Other examples of empirical formulas will be found on Handbook page 278 Handbook page 296... www.industrialpress.com Machinery's Handbook Guide 28th Edition 20 FORMULAS Mathematical Signs and Abbreviations.—E v e r y d i v i s i o n o f mathematics has its traditions, customs, and signs that are frequently of ancient origin Hence, we encounter Greek letters in many problems where it would seem that English letters would do as well or better Most of the signs on Handbook page 2558 will be used . title: Machinery’s handbook 28th guide.
