The nоtched bаr is subjected tо а bending mоment of M = 460 N·m. The mаjor bar width is D = 104 mm, the minor bar width at the notches is d = 100 mm, and the radius of each notch is r = 2 mm. If the maximum bending stress in the bar must not exceed 72 MPa, determine the minimum required bar thickness using Neuber's nomograph (Table 14.3 and Figure 14.10).
