Gage holeswere then drilled in the steel with a ETo. 5ji drill as is generallydone for strain-gage readings. This completed the preparationuntil the observer took charge. However, it was found helpful inobtaining good readings for the observer to go over all the holesand ?:crk them out» with a strain gage before any readings Handling. - At the time of pouring two stirrups or loops wereplaced in the beams about 6 ft., from the ends bywiich the beamscould be lifted. An electric hoist was used to move the beams .end put them in the testing 17stressesinwebrei00lars
