Mechanics of the Girder

Excerpt from Mechanics of the Girder: A Treatise on Bridges and Roofs, in Which the Necessary and Sufficient Weight of the Structure Is Calculated, Not Assumed; And the Number of Panels and Height of Girder That Render the Bridge Weight Least, for a Given Span, Live Load, and Wind Pressure, A The "Mechanics of the Girder" is presented to the public in an unfinished condition, just as it was left at the author's death, in October, 1884. All that then remained to be done was to carry out an example in each of the twelve classes of girders in a manner similar to that of the Brunel Girder in Class I. (Sections 2 and 3, Chapter X.), and the Double Parabolic Bow and Post Truss in Class II. (Chapter XI). Of all these, the Post Truss promised to yield the most prolific results; and it may be possible, before another edition is published, to complete this calculation at least, if not to introduce other examples from the later classes. However, the a priori method of the author is fully set forth previous to the tenth chapter; and it is believed that no one else has as yet published any so satisfactory results from this method, if, indeed, the method has been hitherto attempted with any degree of success.
