The rotating shaft shown in the figure is machined from AISI 1020 CD steel. It is subjected to a force of F = 6 kN. Find the minimum factor of safety for fatigue based on infinite life. If the life is not infinite, estimate the number of cycles. Be sure to check for yielding. The diameter of the bar is 35 mm and the radius of the step down in the shaft is 3 mm. All dimensions listed below are in mm. 25 D. 20- 20 -35 D. 180 - 500 3 R. 280 -175- -50 D. - 25 D. 20 20
