The 0.25-in.-thick bar shown in Figure P5.74 is made of 2014-T4 aluminum (see Appendix D for properties) and will be subjected to an axial tensile load of P = 1,500 lbs. A 0.5625-in.- diameter hole is located on the centerline of the bar. Determine the minimum safe width D for the bar if a factor of safety of 2.5 with respect to failure by yield must be maintained.
