01-01-1918 - 31-12-1918

29 blueprint plates related to the design of duralumin struts and girders. Marked II - Plates. Housed in the original file. The plates depict: Strut curves for plain angles Strut curves for lipped angles Strut curves for plain channels Strut curves for lipped channels Method of failure of girder members The stress distribution in a braced girder Girder bracing Details of test girders Experiments on complete girders in compression Details of 18L type transverse girders "Armstrong" zeppelin type girder Zeppelin L-33 keel corridor girder Zeppelin main longitudinal girder Joint F of main transverse frame Variation of weight of girder for a given crippling load with L/K of complete girder Variation of weight of girder for a given crippling load with S/t of angle member Variation in the weight of different types of box girders, for a given crippling load with l/k Strengths of "A" girders Strengths of "B" girders Variation of weight of girder per 1 ton of crippling load with L/K of complete girder Variation of weight per 1 ton crippling load with l/k of individual channels Strengths of "D" type girders Strengths of "C" type girders Strengths of "E" type girders Strengths of "F" type girders Sketch of "short" wooden girder Experimental results of test on plain channels Experimental results of test on plain angles
