This is the complete question
A component is subjected to a maximum cyclic stress of 750 MPa
and a minimum of 70 MPa. The steel
from which it is manufactured has an ultimate tensile strength, σu,
of 1050 MPa and a measured endurance
limit, σe, of 400 MPa. The fully reversed stress at 1000 cycles is
750 MPa. Using both the Goodman and Gerber
mean stress correction procedures, calculate the component
life.
