Few mechanics are entirely devoid of springs of one sort or another but satisfactory operation rests on details such as spring strength & degree of movement Yet information on calculating & making springs is not easily available This book explains the property of each type of spring plus essential materials & methods Engineers professional or amateur often find designing springs difficult due to the number of variables & the complexity of the formulae The book also introduces the designer to charts & nomograms which greatly simplify the process Tubal Cain draws on several decades of experience in the actual processes & covers the design & manufacture of compression & extension coil springs simple & compound leaf springs torsion springs & torsion bars springs relying on bending actions & a useful graphical method of designing valve springs for IC engines
