Fmax = F and Fmin =-F, where F and the beam's other data are given in the row(s)
assigned from Table P6-6. Find the stress states at points A and B due to this fully
reversed 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 2.5 in bending and 2.8 in torsion.
