The paper showed that by writing the equations for the extreme fibre stresses and the concrete cover requirement in dimensionless form the problem of selecting the design which gives the least area of section, for a given depth, reduces to one of solving five equations for five unknowns.
The paper descriptionbed the construction of the Swaziland Railway, a project unusual in that the territory in which the line was built had no existing railway or railway background.
