The author has availed himself of the opportunity, in this revision, to
give a complete solution of the elastic arch of variable section. The
arch of steel and concrete combined is taken up in detail to illustrate
the general graphical treatment. The method to follow for other arches,
as those of steel, stone or concrete, is at once apparent from the
general solution. The aim throughout has been to give a clear analysis
of principles involved, a knowledge of the fundamental principles of the
equilibrium polygon being alone assumed.....Many of the earliest books,
particularly those dating back to the 1900's and before, are now
extremely scarce and increasingly expensive. We are republishing these
classic works in affordable, high quality, modern editions, using the
original text and artwork.
