Abstract

This strain measuring apparatus shows a device to be press fitted into a hole in a member subject to stress, for the purpose of measuring the strain produced in the member by that stress. The device is a cylindrical shell with a middle portion knurled on its outer surface so that it has an overall diameter slightly greater than the diameter of the hole in which it is to be inserted. A web extends across the interior of the middle portion of the shell perpendicular to its axis. Strain gage elements are attached to the surfaces of the web.
