An apparatus for orienting a test article (80) relative to a loading axis (32) includes a first member (100) and a second member (120). The first member may have a concave surface (102). The second member (120) may have a convex surface (122) configured to engage the concave surface (102) in a manner such that the second member (120) is movable relative to the first member (100). The test article (80) may be coupled to one of the first and second members such that relative movement thereof facilitates general alignment of the test article (80) with the axial loading axis (32). The leveling apparatus may further include a plurality of positioning devices configured to facilitate adjustment of an orientation of the second number relative to the first member (100) such that the alignment of the test article (80) may be adjusted. |
