A 3003-H14 aluminum alloy rod with 0.5 in. diameter is subjected to a 2000- lb tensile load. Calculate the resulting diameter of the rod. If the rod is sub- jected to a compressive load of 2000 lb, what will be the diameter of the rod? Assume that the modulus of elasticity is 10,000 ksi, Poisson’s ratio is 0.33, and the yield strength is 21 ksi.
