Question: given a component is made of material with s60 ksi...

Question details



Given: A component is made of material with S-60 ksi and Se-20 ksi is subjected to afluctuating stress between- = 50 ksi and σ--20 ksi. Find: Determine the following: a) Calsulate the mean and alternating stresses (omGa).Plot the Goodman line and (om ) on the right-hand side of the graph below. Hint: your (o, Ga) should be above the Goodman line. b) Plot the S-N curve on the left-hand side of the graph below c) Calculate the theoretical failure strength (S) of the component under this loading. lmustrate how you determined this on the right-hand side of the plot below. d) Estimate the fatigue life in number of cycles (N) for the component. Ilustrate how you determined this on the left-hand side of the plot below. 75: 2550 + mean stress (ksi) 75 103 109 Number of cycles (N
