The cross-section of a steel specimen measures 1 in. by 0.5 in. When tested in tension, it yielded at a load of 38 kips, and then finally failed at a load of 50 kips. Setting Young’s Modulus equal to 29000 ksi and Poisson’s ratio equal to 0.3, compute the following: (i) Yield strength of the material specimen (ii) Stress at failure (iii) The strain when stress is half the yield stress and (iv) Thickness and width of the specimen when stress reaches half the yield stress.
