Excerpt from Simple Practical Methods of Calculating Strains on Girders, Arches, and Trusses: With a Supplementary Essay on Economy in Suspension Bridges The treatises existing at that time were either too meagre or too mathematical for the average engineering student. One class gave him results without explaining to him how they were obtained, the other, in making the required explanation, bewildered him with mathematical formulæ beyond his comprehension. Several excellent works on this subject having appeared during the last few years, the issue of another from the press might be thought superfluous. I have judged otherwise, because the methods adopted in this little work are mostly original, and, as I consider, simpler than usual. A knowledge of simple equations, excepting on the subject of deflection, where a little elementary trigonometry is required, is the extent of the mathematical attainment required for working out the problems presented in this work to the reader. The article on "Economy in Suspension Bridges" from "Engineering" is added as a supplement to the chapter on Suspension Bridges.
