Abstract

A flat disc is pressed into a bore provided in a structural member that is under stress. The disc has peripheral teeth that permit to be press fit in the bore and strain gage elements oriented mutually perpendicularly to one another provide inputs to a bridge circuit for monitoring the strain in the member at a preselected location.
