Method of Determining the Weights of the Most Important Simple Girders
A 1931 NASA technical report on methods for calculating the weights of simple girders, issued through the NASA Technical Reports Server for aeronautical engineers and structural designers. The single picture is a line graph of two curves, f''(ε) and f'(ε), plotted against the ratio ε from 0 to 1.0 with a solid curve and a dashed cantilever-alone curve, plus an equation block; it offers a designer little beyond a clean, sparse engineering chart style with thin black lines on a gridded field.
