Excerpt from New Formulas for the Loads and Deflections of Solid Beams and GirdersThe aim of the Author, when he commenced the Essay which he now ventures to submit to the criticism of his fellow engineers, was to obtain a set of formulas for the loads and deections of solid beams, strictly based on the assumption ut tensio sic m'a, but not vitiated by the absurd restriction to the full meaning of the maxim, which seems hitherto to have been the stumbling-block in the way of any honest investigation of the subject, viz. That the neutral surface must in all cases pass through the centre of gravity of every section of the beam.The clear and simple meaning of the maxim is, that if any given force is capable of producing a certain amount of exten sion or compression, double the force would produce double the amount of extension or compression; not that the absolute amounts of extension or compression produced by the same force would be equal - an assumption which is identical with the assumption that the neutral surface passes through the centre of gravity of each section.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
