Question

Required information The rotating shaft in the given figure is machined from AISI 1020 CD steel. It is subjected to a force of $F = 2$ kN . Find the minimum factor of safety for fatigue based on infinite life. Be sure to check for yielding. Dimensions in millimeters Determine the endurance limit for this material as well as the value after correction for surface finish, sizing, and loading. The endurance limit for this material is 197.5 MPa. The endurance limit after correction is 158.4 MPa.

Step 1

For AISI 1020 CD (Cold Drawn) steel, a typical value for $S_{ut}$ is around 440 MPa. For steels, the endurance limit ($S_e'$) is generally estimated as half of the ultimate tensile strength, provided $S_{ut} \le 1400$ MPa. So, $S_e' = 0.5 \times S_{ut}$ $S_e' = Show more…
