<p>A support system (30, 31, 35, 40, 50, 60) provides a stable reference frame to support an extensometer assembly (25) that measures both axial and torsional strains in a specimen (13). The reference frame (30, 31, 35, 40, 50, 60) is made so that it will retain an optimal relationship between the specimen (13) and the test machine (10) which is used for loading the specimen. The reference frame is made so that it will not substantially change position in relationship to the specimen (13) during the specimen loading, or cross talk from one measurement axis to the other, while accomodating load frame deflections during the application of axial and torsional loads on the specimen (13).</p> |
