Suspension Bridges and Cantilevers

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. In recent engineering literature there is frequent reference to the question of the relative adaptability of the cantilever and suspension bridges to long span construction and to the dearth of adequate data from which the limiting and economic spans for the two bridge-types might be deduced. In order to supply this deficiency and to determine as definitely as practicable the length of span at which the suspension bridge becomes economically superior to the cantilever, the author has undertaken the investigations which are summarized in the following pages.<br><br>In connection with these investigations there have arisen several subsidiary problems of design.
