given in the row(s) assigned from Table. Find the stress states at points A and B due to this repeated loading and choose a ductile steel or aluminum material specification that will give a safety factor of 2 for infinite life if steel or N= 5E8 cycles if aluminum. Assume a geometric stress-concentration factor of 2.8 in bending and 3.2 in torsion.
