Publisher's Synopsis
Excerpt from Morrison's Spring Tables: A Handbook for Engineers, Students and Draughtsmen
IN offering this book to the public, the author desires to call attention to the general scheme which has been followed.
Springs fall naturally into two classes, light and heavy: in the case of helical springs called Wire and bar; in elliptical springs called sheet and plate. In the following pages the writer has considered a helical spring Whose bar is less than one-sixteenth of an inch in diameter, or an elliptical spring Whose plate is less than one-sixteenth of an inch in thickness, to be a light spring.
In helical springs the ratio between the diameter of the bar (or similar dimension in other than circular sections) and the mean diameter of the spring forms the basis of calculation in estimating the various properties of the spring. In elliptical Springs the basis of calculation is the ratio between the thickness of the plate and the span or net length of the Spring. The span or net length of a spring is the distance between centers less the Width of the band.
