The shаft (OA) is mаchined frоm 1045 cоld-drаwn steel (Sy = 530 MPa, Sut = 630 MPa) tо the dimensions provided. The shaft rotates at constant speed of 1800 rpm and is supported by bearings at O and C. The belt tensions on pulleys A and B result in a constant torque on the shaft of 250 Nm and a completely reversing bending moment at critical point C of 500 Nm. The transition between diameters at point C has a fillet with a 2-mm radius. Determine the following: The modified endurance limit (Se) for this application with 95% reliability The factor of safety for first-cycle yielding (ny) The factor of safety with respect to infinite life (nf) using the Modified Goodman criteria Write down all your work to scan and submit. Se = [Se] MPa (round to 0 decimal places)ny = [ny] (round to 2 decimal places)nf = [nf] (round to 2 decimal places) LOB = 230 mm, LBC = 280 mm, LCA = 300 mm, dOB = 42 mm, dBC = 48 mm, dCA = 40 mm
