Abstract
A measuring shaft intended to be fixed in a hole is equipped with strain gauges or similar devices for sensing a load. The inner end of the measuring shaft is threaded to engage with threads provided in the bottom of the hole, and the outer end of the measuring shaft is fixed in relation to the hole so that the measuring shaft like a part unseparated from the walls of the hole but nevertheless detachable, accompanies the motions of the said walls.
