A rather extensive treatment of the stresses in fuselage main bulkheads is given in NACA Technical Report No. 509. The Least work equations developed in the report are for the most general case. The examples given are for concentrated loads, which are in balance, and applied. at various points on a circular bulkhead.
\r\n\r\nNow the shear loads which are transmitted by the skin and stiffeners to a main ring exist in the form of a distributed load which varies around the bulkhead.
\r\n\r\nThe purpose of\u00b7 this paper is to present an analysis pf a main bulkhead in which the wing reactions a.re balanced by a varying distributed load around the bulkhead. The shear distribution although not exact because of the interaction of skin and stiffeners, seems however, closer to the actual existing conditions than would be a case in which the shear loads are treated as concentrated loads.
\r\n\r\nTo somewhat simplify the energy equations the bending and torsional shears were treated separately, the work due to the shear and axial load deformations were also neglected. The error introduced is relatively small.
\r\n\r\nIn the particular airplane to which this solution was applied 80% of the fuselage cross section area consisted of skin and the remaining 20% consisted of stiffeners. Hence the shear transferred by the skin is of major importance.
\r\n\r\nThe case chosen as an illustrative example is an unsymmetrical condition since this is the most general case.

\r\n\r\nBefore beginning the tests it was necessary to design and construct a new reducing motion for the indicator, the old one having proven unsatisfactory. This\r\nnew reducing motion, drawings of which may be found in the appendix, consists of an eccentric mounted on the main shaft, connecting rod, crosshead guides, etc. Care was taken in the design of this motion to keep the ratio of the throw to the length of the connecting rod the same as that of the engine itself, this being necessary in order to obtain an accurate reproduction of the mot ion of the piston.
\r\n\r\nDuplicate tests were made at loads ranging from zero to full load of the engine and a comparison of the results obtained will be found in the balance of this thesis.
\r\n\r\nDifficulties encountered in the construction and attachment of the reducing motion and the limited time available for this thesis made it impossible to secure\r\nenough data from which to draw positive conclusions. However, the results obtained are sufficient to indicate what may be expected, from the use of water injection devices.

\r\n\r\nCurves of the various fuels were to be obtained from: the compress ion pressures as abscissae and pounds of fuel per delivered horsepower per hour as ordinates. These curves were to be plotted from the results of a least two tests at an interval of one delivered horsepower apart ranging from zero to the maximum output of the engine; this series being re2eated at each of the four or six compress ions obtainable. Thus with a five brake horsepower engine, which was used, there would be two tests at each horsepower, at each compression, and with each fuel; making in all; assuming five different compression pressures ranging between forty-five pounds per square inch (Gage) and one hundred and ten pounds per square inch (Gage) two (tests) X five(horse power ) X five (compression pressures) X four (fuels) equals two hundred (Total number of tests).
\r\n\r\nThis figure is conservative as it would have required more than two tests in many cases in order to get anything like checking results.
\r\n\r\nAll tests were to be of not less than an hour\u2019s duration and in some cases it was hoped to run longer ones in order to procure more accurate indicated horsepower readings.
\r\n\r\nThe curves thus obtained and plotted would show at what power the maximum economy occurred for each fuel. Such curves are not to be found at this time in any source obtainable.

\r\nThis, together with the fact that the regular College Course as given must of necessity deal only with fundamentals, with but few digressions into the detail of any specific class of phenomena, caused me to selected for my thesis the investigation of; first, polyphase currents in general and second, a few specific instances of loading one phase only of a three phase system.

For expenditures in connection with such a report Mr. Thum very kindly offered to deposit a certain sum with the Institute. This offer was taken under consideration by the Faculty, and upon investigation of the time at the disposal of the various students, the problem was placed before the Senior Class as an elective subject for a thesis.
\r\n\r\nThis offer the Senior Class was very glad to accept, and work was commenced at the beginning of the second semester of the year 1910-1911. A rough outline of the various items to be taken up in such a report was furnished by Prof. Sorensen and later suggestions were made by Dean Damon. As actually accomplished, the work covers a detailed description of the plant and distribution system with drawings and maps, an appraisement of the property, a summary of segregated costs, capacities, etc., a statement of the general methods employed in financing public utilities, various suggestions as to possible improvements, and a partial description of the accounting system in use by the Municipal Lighting Works.
\r\n\r\nThe figures found in the summary may be considered as accurate to within five per cent. of the cost of the plant altho sufficient time was not available for a detailed study of this phase of the problem. The idea has been rather to obtain data from which rough estimates of similar equipment could be made.
