This paper is the first of three papers on a refined internal strainwire technique. Availability of sensitive data-acquisition equipment has made possible a detailed investigation that resulted in reductions in both gage length and excitation voltage with little reduction in the quality of the information. The method of measuring internal strains by embedded lengths of strain-gage wire has been extended to the construction and evaluation of strain rosettes. Experimentally measured principal strains on an interior plane of a compressed square prism are compared for statistical and theoretical consistency.
