✦ Synopsis

The load W~, produces at the distance z from the end of the cantilever arm a moment

Changing Z to x and using a more accurately descriptive index for Mr, we obtain

M~xtc = #X' { Ax (x + "Is) + 2B (2x + 31s)

The symbol M~x ' c indicates the moment at the distance x from the end of the cantilever arm produced by the weight of the cantilever truss required to carry the moving load/~ per foot of bridge. The effect of the weight of the suspended span is not included.

The load //V~ produces at the distance x from the end of the cantilever arm a shear or fo' { S~C = # Ax (ls + X) + B (x +

THe-purpose of this paper is to describe a reliable method of finding the most economical general dimensions of long-span ordinary truss and cantilever bridges, and incidentally to give formulas which express their weight as a function of the loads, the unit stresses, and the general dimensions. In
