The notched bar is subjected to an axial tensile load of P = 26.4 kN. 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 tensile stress in the bar must not exceed 79 MPa, determine the minimum required bar thickness using Neuber’s nomograph (Table 14.3 and Figure 14.10).

The notched bar is subjected to a bending moment of M = 640 N·m. The major bar width is D = 180 mm, the minor bar width at the notches is d = 144 mm, and the radius of each notch is r = 2 mm. If the maximum bending stress in the bar must not exceed 78 MPa, determine the minimum required bar thickness using Neuber’s nomograph (Table 14.3 and Figure 14.10).

The beam has a rectangular cross section with D = 44 mm, d = 40 mm, r = 16 mm, and a thickness of 6 mm. If M = 20.6 N·m, determine the maximum normal stress at the section through the base of the fillets using Figures 14.24 and 25.

Consider a circular hole in a plate with stresses σx = 24 MPa and σy = 91 MPa applied to the plate edges. Determine the maximum tensile stress in the plate.

The tension member has a rectangular cross section with D = 75 mm, d = 30 mm, r = 22.5 mm, and a thickness of 2 mm. If P = 3.1 kN, determine the maximum normal stress at the section through the base of the fillets using Figure 14.16.

The notched bar is subjected to an axial tensile load of P = 12.2 kN. The major bar width is D = 40 mm, the minor bar width at the notches is d = 36 mm, and the radius of each notch is r = 2 mm. If the maximum tensile stress in the bar must not exceed 77 MPa, determine the minimum required bar thickness using Neuber’s nomograph (Table 14.3 and Figure 14.10).

The beam has a rectangular cross section with D = 55 mm, d = 50 mm, r = 35 mm, and a thickness of 6 mm. If M = 22.4 N·m, determine the maximum normal stress at the section through the base of the fillets using Figures 14.24 and 25.
