A 1020 steel shaft
3. A 1020 steel shaft has a corrected real endurance limit of Se 40 ksi and a tensile strength of Sut 64 ksi. The shaft is loaded in bending and torsion such that Ma 500 lbf.in, and Tm 300 lbf.in, Mm Ta 0. The stress concentration factors were determined to be Kr 2.25, and Kf 1.75. Provided the design engineer choose a diameter of d 1.0 in, determine the factor of safety n of the shaft...
