Abstract
An extensometer assembly measures axial strain, torsional strain, and various combinations of these strains in a specimen on which the extensometer is mounted, through the use of two extensometers on opposite sides of the specimen coupled by a cross-beam. Connecting assemblies are used to eliminate flexibility in unneeded axes to thereby minimize the opportunities for unwanted signals to occur. The mounting frame is stiff in all axes which are not necessary for measurement. The frame is soft in necessary axes for operation.
