Gauge for measuring bending of structures.

摘要

A gauge for measuring bending of structures comprises a bending bar which may be attached to the structure so that it bends in response to bending of the structure and having means for measuring bending of the bar whereby measurement of bending of the bar enables bending of the structure to be determined. Preferably, the bar is hollow with strain gauges on its inner surface and is attached so that at least part of it may move longitudinally along its axis with respect to the stucture.
