An ASTM A36 steel having a yield strength of 235 MPa, a tensile strength of 640 MPa, and an endurance limit of 210 MPa is subjected to a cyclic loading. Using the Goodman diagram, predict whether the material has an infinite fatigue life, or whether it will fail by yielding or fatigue, when the cyclic stress is between:
(i) 0 and 250 MPa.
(ii) 95 ± 220 MPa
