**Educational Content on Fatigue Stress Concentration in Shafts****Problem Statement:**A shouldered machine shaft is subjected to bending, as illustrated. The shaft is constructed from AISI 1015 cold-drawn (CD) steel with an ultimate tensile strength (\(S_{u,T}\)) of 390 MPa. The dimensions for this shaft are specified as follows: the larger diameter \(D = 200 \, \text{mm}\), the smaller diameter \(d = 190 \, \text{mm}\), and the fillet radius \(r = 28.5 \, \text{mm}\). The task is to determine the fatigue stress concentration factor using the Neuber Equation.**Diagram Explanation:**The accompanying diagram shows a shaft with two distinct diameters, creating a shoulder. The shaft is subject to a bending moment denoted by \(M\). Dimensions are marked: \(D\) is the diameter of the larger section, \(d\) is the diameter of the smaller section, and the transition between these sections is rounded with a radius \(r\). The arrows indicate the application of bending forces.**Multiple Choice Options:**- a. 1.3607- b. 1.3308- c. 1.5186- d. 1.3698**Objective:**Using the provided information and applying the Neuber Equation, determine which fatigue stress concentration factor is correct from the given options.

The stress concentration factor for r/d = 0.15 and D/d = 1.05 form the stress concentration factor…
