A non rotating aluminum rod has diameter of 1.5 inches. It is loaded in fully reversed torsion at a temperature that can go as high as 300 F. The steel has ultimate tensile strength of 45 kpsi. You may use 99% reliability. a) Determine the uncorrected fatigue strength Sf’b) Determine the corrected fatigue strength Sfc) Develop an equation for the corrected S-N diagram and plot it (logarithmic axes would make it look like the ones in the book) for up to 108 cycles. d) If a certain application of this rod induces fully reversed bending stress of 25 kpsi, what would be the life of the rod (in cycles)?
