Question
![A bolt is used for a connection where the initial mean stress on the bolt is 30 MPa. The bolt is
exposed to the repeated loading (Omean = Galternating) as shown in the figure below. If the safety factor
of the design for fatigue failure is N = 2, calculate the alternating and mean stresses acting on the
bolt? (Se 150 MPa, Sut = 300 MPa)
(hint: observe that the loading line makes 45° angle with the horizontal line since mean = alternating)
