I should like to contribute to the discussion on compression members, started by my friend Mr. Ewart S. Andrews. My contribution will be along the lines of an article of mine published in R. R. Age-Gazette, July 2nd, 1909, and re-printed in my book “Steel Designing.” Engineers have almost universally ignored my attack of the problem, though it furnishes an exact theoretical basis for the straight-line formula as applied to a hinged-end column. In fact it proves that the straight-line formula is the one logical formula for structural columns, or those limited to 120 or 150 radii in length.
The accompanying sketch shows the general construction of a steel-framed Market Building, which was erected by a continental firm at Dar-es-Salaam, in the pre-war days, when that town was in German territory. H.V. Crabtree
To those who are not engaged in gas engineering, it is difficult to fully appreciate the wide range of training and experience that is necessary in order to deal satisfactorily with the problems which arise in the design of plant and apparatus for the manufacture of coal gas. The necessary plant and machinery call for knowledge and experience in the design of structures and their foundations which may involve anything from a simple mass of concrete to a complicated arrangement of reinforced rafting or piling-a knowledge of civil, structural, mechanical and chemical engineering, and also a knowledge of the application and limitation of steam and gas engines, electrical apparatus and hydraulic power.
