The notched bar is subjected to a bending moment of M = 500 N·m. The major bar width is D = 120 mm, the minor bar width at the notches is d = 96 mm, and the radius of each notch is r = 3 mm. If the maximum bending stress in the bar must not exceed 71 MPa, determine the minimum required bar thickness using Neuber’s nomograph (Table 14.3 and Figure 14.10).
