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...

For a 60 degree strain rosette shown in the figure, prove that the sum of the three measure- ments is independent of the orientation of the rosette, i.e., Ei + €2 + €3 = 3€ avg (1) where €1, €2, and Ez are the normal strains measured by the gages 1, 2, and 3, respectively. In addition, Eavg is the abcissa (x-coordinate) of the center of the corresponding Mohr's circle. 600 Figure 3: Problem 4
