9. For a certain high-temperature alloy, failure was reported after 4100 hours at 680°C when subjected to a stress level of 270 MPa. If the same stress was applied at 725°C, how long would the sample be expected to last? State all assumptions that you must make to allow you to make this determination. Comment on your answer
