The strains on the surface of an experimental device made of pure aluminum ( E=70 GPa, v =0.33 ) and tested in a space shuttle were measured by means of strain gages. The gages were oriented as shown in the figure, and the measured strains were 6 a 1100 10 ε − = × , and 6 b 1496 10 ε − = × , 6 c 39.44 10 ε − = − × . What is the stress x σ in the x-direction ?
