Final answer:
The factor of safety for fatigue analysis using the Morrow criterion is determined by dividing the endurance limit of the material by the maximum stress experienced by the material.
Step-by-step explanation:
The factor of safety for fatigue analysis using the Morrow criterion can be determined by dividing the endurance limit of the material by the maximum stress experienced by the material. The endurance limit is the maximum stress the material can withstand for an infinite number of cycles without failing. The maximum stress is typically determined through testing or calculations based on the loads and geometry of the component.
For example, if the endurance limit of a material is 50 MPa and the maximum stress experienced by the material is 25 MPa, then the factor of safety would be 50 MPa / 25 MPa = 2.
