An aluminum alloy with a yield strength of 350 MPa and a tensile strength of450MPaexhibits a Basquin's Law of σarNf0.1=750MPa. If the alloy is subjected to zero-to-tension fatigue loading, with σmax= 250 MPa, in how many cycles will the alloy fail?(2.3 x 106cycles)After 1.0 x 106cycles at this loading, it is decided that the lifetime needs to be extended by an additional 4.0 x 106cycles in "zero-to-tension" loading. What is the new maximum stress that can be appliedin zero-to-tension loading?(115MPa)
