Final answer:
The fatigue notch factor cannot be determined with the provided details. Additional information about the notch and material properties is needed to perform the calculation.
Step-by-step explanation:
The fatigue notch factor is a coefficient used in mechanical engineering to account for the increase in fatigue stress concentration caused by notches, grooves, or holes in a material. However, the provided information does not give the necessary details to calculate the fatigue notch factor of the plate. Normally, to determine the fatigue notch factor, additional information such as the shape and size of the notch, the material properties, and the stress concentration factor (Kt) are required. Because this information is not provided, we cannot directly calculate the fatigue notch factor.
