In the 7th Edition of "Fundamentals of Machine Component Design" (Juvinall and Marshek),
Figure 8.6 is located on page 216.
Details of Figure 8.6:
● Title/Caption: "Approximate Fatigue Strength (σsf) for Reversed Bending."
● Content: This figure provides a plot used to estimate the fatigue strength of various
materials (such as aluminum alloys, magnesium alloys, and copper alloys) at 108 or
5×108 cycles when specific test data is unavailable.
● Context: It immediately follows the S−N curve for steel (Figure 8.5) within Section 8.3:
Standard Fatigue Strengths (Sn′) for Rotating Bending.
