In the figure, a steel shaft with ball bearings at points A and D, with cross-section narrowing at points C and D, a single load of 2 kN from B point not to rotate with the shaft, 0.1 kN/mm between points D and E so that it does not rotate together with the shaft. A distributed load of ' is applied. The shaft surface is ground and the shaft operates at room temperature with 50% reliability. Calculate the fatigue life of the shaft, taking into account the cross section narrowing point where the maximum moment occurs. All radus on the shaft are R2 mm.(Sut=690 MPa,f=0.9)
