THE methods of wing stress analysis at present in use have in most cases been developed on the assumptions that the ribs are rigid in their own planes, and that they may be considered equivalent to an infinite number of infinitely thin ribs, infinitely closely spaced. The problem may then be treated by the methods of the calculus, as was done, for example, in an article by the writer in AIRCRAFT ENGINEERING, January and February, 1943. A more recent and much more comprehensive paper on the same subject has been published by J. Hadji‐Argyris and P. C. Dunne in the R. Ac. Society Journal, February, September and November, 1947, and May and June, 1949.
