Question 7 (15 points) The same shaft with a keyway, as in the previous question, is considered here again. The diameter of the shaft is d=30mm and the keyway fillet radius is r=3mm. Suppose that the static stress concentration factor is k =2.06 and the shaft is made of wrought steel with UTS-600 MPa. Using the table shown below, find the fatigue stress concentration correction factor (Cc). (Hint: round-off your answer to 4 decimal places). d/4 d r d/
