Prob. 2.13-5. A titanium-alloy bar has the following original dimensions: a = 10 in., b = 4 in., and c subjected to stresses x 14 ksi and y = : 2 in. The bar is 6 ksi, as == indicated in Fig. P2.13-5. The remaining stressesz, Txy, Txz, and Tyzare all zero. Let E : 16 103 ksi and v = = 0.33 for the titanium alloy. (a) Determine the changes in the lengths: Aa, Ab, and Ac, where a*= a + a, etc. (b) Determine the dilatation, Ev. C* b* Z 14 ksi 6 ksi x
