1. A strain gage rosette is an electromechanical device that can measure relative surface elongation on three directions. Bonding such a device to the surface of a structure allows determination of normal strain along the gage arms. Such a rosette is mounted on the surface of a stress-free elastic solid as shown at the right. Upon loading, the three gage readings are 30 a30 Ea-300 x 10-6, ε,-400 x 10-6, ε.-100 x 10-6 Assuming the material is steel with E-207...
