A forged 0.85 inch diameter steel bar is sent to test center in a manufacturing factory for safety test. Before the experiment is performed, you wish to have a model of the strength over use and fatigue strength with an infinite life with 99% reliability. The key material properties of this steel bar are S,-160 ksi and Sy = 95 ksi. Plot on the semi-log graph below the estimated S-N curves for: (a) Axial load (b) Bending load (c) Torsional...

Problem 1 (10 points): A rotating shaft (D = 3.5 in) is machined out of steel (S.-97 ksi and S,-68 ksi) and experiences both bending and axial loading during service at room temperature. Determine the endurance strength for 50% reliability.
