Developments in the Useful Circular Nomogram

Abstract

The particular type of alignment diagram for the function U · V = W in which the U and V scales lie on the circumference of the same circle and the W scale along a diameter is developed in detail. The forms of the diagram for which certain intervals on these scales are maximized in their spread are derived and described. Such maximized diagrams, it is found, have certain characteristic properties of symmetry. These developments are illustrated with examples.
