A machine part has Sut=530 MPa, a fully corrected endurance strength of Se=210 MPa, and f=0.9. The part will first be in service at ±350 MPa for 5*103 cycles, before the loading is adjusted to ±260 MPa for a further 5*104 cycles. The load will then be changed one last time to +225 MPa. Estimate the remaining service life. Hint: Use Miner's Rule.
