A cylindrical shaft is subjected to alternating stress of 100 MPa. Fatigue strength to sustain 1000 cycles is 490 MPa. If the corrected endurance strength is 70 MPa, What will be the estimated shaft life in revolutions? If the fatigue strength of the bar to withstand N cycles is 100 MPa then what will be the value of N (To the nearest integer)?
