| C O P Y. 174 X380 R22/P 11.10.13. To Na.{Mr Nadin} from R.{Sir Henry Royce} Copy to J.{Mr Johnson W.M.} " " Wor.{Arthur Wormald - General Works Manager} I am of the opinion that Prof. Arnold is sound on the question of fatigue testing and that this system of bending the piece in the way he suggests does give better result than any reversal or impact testing that we know of, and that we ought to adopt it if we find no better. It should be borne in mind that it is of little value without static testing also but this we have already arranged to install. I think, however, that the revolving test is excellent for finished pieces such as we have used it for and that we should continue to do so. We ought also to have the Avery notched bar impact tester or another because this is so simple and we may find that it agrees with the more complex scheme set for above. R.{Sir Henry Royce} COPY. | ||
