aches a fixed ended condition with the increase in tensile loading. A calculation of the beam action is therefore impracticable and the only satisfactory method of finding the correction to be applied is to calibrate the instrument for the various sizes of wires and cables upon which it is to be… … To obtain these curves the cable or wire was suspended from a beam and the desired amount of load applied by the use of dead weights, thus insuring a constant load on the wire and the elimination of all sources of error except that of the beam action of the wire or cable. Various increments of load…
