A Handy Testing Machine: The Hounsfield Tensometer Provides a Suitable Apparatus for Routine and Bulk Testing Available to Purchase

THERE is no doubt that with the modern high‐grade materials in use in aero‐plane construction, mechanical testing has become of the greatest importance. It will be remembered that a series of articles entitled “The Testing of Metallic Materials” by Mr. E. Skerry, which dealt exhaustively with all aspects of this subject, was published in Air‐craft Engineering, Vol. VI, March, April, and May, 1934, pp. 77–85, 111–114, and 139–140. In those articles all the recognised standard tests for metals were detailed, and the principal types of machine available described.
