The cold-drawn AISI 1040 Q&T at 205 ◦C steel bar shown in the figure is subjected to a completely
reversed axial load fluctuating between 28 kN in compression to 28 kN in tension. Estimate the
fatigue factor of safety based on achieving infinite life, and the yielding factor of safety for the
following cases. If infinite life is not predicted, estimate the number of cycles to failure.
a) for the part given in Fig 2(a) and
b) for the part given in Fig. 2 (b) using the same dimensions (W=25mm, r=3mm, the thickness of 10
mm)

It's made from a steel with yield strength (Sy) of 42 ksi and ultimate tensile strength (Sut) of 76 ksi. The diameter is 0.42 in and b = 1.75 in, with the load P fluctuate between 15 lbs (tension) and -5 lbs (compression). Using the modified Goodman or Gerber criterion, determine the fatigue factor of safety based on infinite life. If infinite life is not predicted, estimate the number of cycles to failure. Also check for yielding.arrow_forward
