Preface to the SI Edition This edition of Mechanics of Materials has been adapted to incorporate the International System of Units (Le Syste`me International d’Unite´s or SI) throughoutthe book. Le Syste`me Internationald’Unite´s TheUnitedStatesCustomarySystem(USCS)ofunitsusesFPS(foot–pound– second) units (also called English or Imperial units). SI units are primarily the units of the MKS (meter–kilogram–second) system. However, CGS (centimeter–gram–second) units are often accepted as SI units, especially in textbooks. Using SI Units inthis Book Inthisbook,wehaveusedbothMKSandCGSunits.USCSunitsorFPSunits usedintheUSEditionofthebookhavebeenconvertedtoSIunitsthroughout the text and problems. However, in case of data sourced from handbooks, governmentstandards,andproductmanuals,itisnotonlyextremelydi‰cultto convertallvaluestoSI,italsoencroachesupontheintellectualpropertyofthe source.Also,somequantitiessuchastheASTMgrainsizenumberandJominy distancesaregenerallycomputedinFPSunitsandwouldlosetheirrelevanceif converted to SI. Some data in figures, tables, examples, and references, there- fore,remainsinFPSunits.Forreadersunfamiliarwiththerelationshipbetween the FPS and the SI systems, conversion tables have been provided inside the frontandbackcoversofthebook. To solve problems that require the use of sourced data, the sourced valuescanbeconvertedfromFPSunitstoSIunitsjustbeforetheyaretobe used in a calculation. To obtain standardized quantities and manufacturers’ data in SI units, the readers may contact the appropriate government agen- cies or authorities intheircountries/regions.
