Q1/A short post constructed from a hollow circular tube of aluminum supports a compressive load of 26 kips shown in fig.1. the inner and outer diameters of the tube are di = 4.0 in and d2 = 4.5 in . respectively , and its length is 6 in. The shortening of the post due to the load is measured as 0.012 in . Determine the compressive stress and strain in the post? (10 Marks) 26 k 16 in.
