A bar of rectangular cross section 20mm × 5mm with a central hole of diameter 4mm is subjected to a tensile force F which fluctuates between maximum and minimum values of 10 kN and 8 kN respectively. Determine the safety factor against eventual fatigue failure with a reliability of 50% if the bar is machined from steel with Sut = 324 MPa and sY = 210 MPa.
