ABSTRACT:
A sample holder for use with a bending measuring system. A probe shaft is disposed in an elongated tube. A probe tip is removeably mounted at one end of the probe shaft. The other end of the probe shaft is adapted to be fixed to the bending measuring system. A double knife edge platform supports a sample at each end and the probe tip contacts the sample at its center. Proper alignment between the sample and probe tip is obtained by having means which permit radial adjustment of the platform and rotation of the probe shaft about its central axis.
