Abstract
An extensometer assembly accurately measures axial strain, torsional strain and various combinations of these strains in a specimen on which the extensometer assembly is mounted. The torsional strain measurement is made by measuring angular displacement perpendicular to the longitudinal axis of the specimen with one extensometer at the same time separately measuring the elongation of the specimen with a separate extensometer linked to the torsional measuring extensometer by supports having the necessary degrees of freedom so that readings from the respective extensometers are not subjected to excessive 'cross talk', and at the same time torsional movement between the extensometers about an axis perpendicular to the longitudinal axis of the specimen is resisted.
