A shaft fracture may have both torsion and bending fatigue forces applied to it. When this occurs, the orientation of the fracture face may vary from 45 degrees to 90 degrees with respect to the shaft centerline. The shaft shown in Figure 5 combines dominant bending with torsion, so the fracture is closer to 90 degrees.
