Unpublished paper, 'On the cause and theoretic value of the resistance of flexure in beams subject to transverse stress' by W H [William Henry] Barlow
Reference number: AP/52/1
Date: 1870
Description
Barlow refers to his previous papers, read in 1855 and 1857, wherein he described experiments showing the existence of an element of strength in beams, which varied with the degree of flexure, and acts in addition to the resistance of tension and compression of the longitudinal fibres (see PT/51/1 and PT/58/8). It was pointed out that the ratio of the actual strength of solid rectangular beams to the strength as computed by the theory of Liebnitz is, In cast iron, as about 2 1/4 to 1. In wrought iron as 1 3/5 and 1 3/4 to 1. And in steel, as 1 3/5 and 1 3/4 to 1. The theory of Liebnitz assumes a beam to be composed of longitudinal fibres only, contiguous, but unconnected, and exercising to mutual lateral action. But it remarked that a beam so constituted would possess to power to resist transverse stress, and would only have the properties of a rope.
Annotations in pencil and ink throughout. Includes three figures of beams and an additional eight geometrical diagrams in the text.
