8.23 A two-element rectangular strain gage rosette is mounted on the outer surface of a solid circular shaft of diameter d which is loaded by a torsional moment T. Show the orientation of the gages which will provide the maximum tensile and compressive strains on the gages. If the tensile gage and compressive gages are connected to adjacent arms of a half-bridge circuit, what is the indi- cated output strain in terms of T, d, and the shaft material properties E and v? Does this arrangement provide temperature compensation?
