7-2 The section of shaft shown in the figure is to be designed to approximate relative sizes of d = 0.75D and r = D/20 with diameter d conforming to that of standard metric rolling-bearing bore sizes. The shaft is to be made of. SAE 2340 steel, heat-treated to obtain minimum strength in the shoulder area of 1226-MPa ultimate tensile strength and 1130-MPa yield strength with a Brinell hardness not less than 368. At the shoulder the shaft is subjected to a completely reversed bending moment of 70 Nm. accompanied by a steady torsion of 45 Nm. Use a design factor of 2.5 and size the shaft for an infinite life.
