| 4. by Frank M.{Mr Moon / Mr Moore} Lewis, (a paper read before the Society of Naval Architects and Marine Engineers, New York, 1925) because this treatment embraces the consideration of Minor Criticals. All the recent work with the R.A.E. torsiograph has substantiated the soundness of the methods outlined in this paper - apart from the hysteresis calculations which are still tentative.
