During a compression test of a concrete cylinder, the height of the cylinder is decreased by 0.0072 inch and the diameter increases by 0.00054 in.  The cylinder had an original height of 12 inches, an original diameter of 6 inches, and is made from low strength concrete.  Given a compressive force of 52 kips, determine The compressive stress in the cylinder The axial strain in the cylinder Poisson’s ratio
