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)
