The fluctuating stresses listed in the table are found at a critical location of a component made of steel with Se= 40 ksi, Sy = 80 ksi, Sut = 110 ksi and f= 0.87. These stresses are applied on the part within 10 s. What is the accumulative damage of this part? What is the life of the part in hours if this stress pattern continues to repeat for the remained of the part's life? Use Goodman criterion and Miner's rule in your solution.

Question
The fluctuating stresses listed in the table are found at a critical location of a component
made of steel with Se = 40 ksi, Sy = 80 ksi, Sut = 110 ksi and f= 0.87. These stresses are applied
on the part within 10 s. What is the accumulative damage of this part? What is the life of the
part in hours if this stress pattern continues to repeat for the remained of the part's life? Use
Goodman criterion and Miner's rule in your solution.
