Publisher's Synopsis
Excerpt from On the Strength of Materials: Containing Various Original and Useful Formulae, Specially Applied to Tubular Bridges, Wrought Iron and Cast Iron Beams, Etc
The railway system in this country has recently given rise to a new and important principle of construction, - that of tubular beams; and the facts elicited by the experiments made on this subject have placed in the hands of the mathematician new and valuable data relative to the strength of materials. Mathematicians had long known, that in order to attain the condition of maximum strength, with a given amount of material, in a beam subjected to transverse strain, the material in the section should be so distributed, that when it is about to yield by the force of compression on the upper side of the beam, it should at the same time be upon the point of yielding to that of extension on the under side. If the resistance of the material to compression were in all cases equal to the resistance which it presents to extension, then it is obvious that the form answering to maximum strength would be that in which the material would be equally accumulated towards the upper and under sides of the beam. But this is not generally the case. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
