In fatigue tests on a certain steel, the endurance limit was found to be 1000 MPa for R = 0 (tensile-release) (σ a = σ m = 500 MPa) and 1000 MPa for R = -1 (fully reversed cycling). Calculate whether a bar of this steel would fail by fatigue if it were subjected to a steady stress of 600 MPa and a cyclic stress of 500 MPa.
