Sylphon diaphragms : a method for predicting their performance for purposes of instrument design (open access)

Sylphon diaphragms : a method for predicting their performance for purposes of instrument design

Here, the purpose is to show that the characteristic performance of a syphon diaphragm can be predicted from a knowledge of its stiffness and of its dimensions. The proof is based on a mathematical analysis of this type of diaphragm, together with enough experimental data to prove the validity of the assumptions and the sufficiency of the analysis. Equations are developed for the performance of syphons under various conditions of loading, both for concentrated loads and for hydrostatic pressure.

Notes on the Design of Latticed Columns Subject to Lateral Loads (open access)

Notes on the Design of Latticed Columns Subject to Lateral Loads

"No rational column formula has yet been developed which gives results which are sufficiently precise for the design of airplane members, and consequently it is necessary to fall back upon experimental testing. In order to derive the maximum benefit from experiments, however, it is necessary that the experiments be guided by theory. It is the object here to modify existing formulae that may be obtained with a minimum number of tests" (p. 1).
