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.

The tension member has a rectangular cross section with D = 56 mm, d = 40 mm, r = 8 mm, and a thickness of 3 mm. If P = 1.4 kN, determine the maximum normal stress at the section through the base of the fillets using Figure 14.16.

For the flat bar in Figure A of Table 14.3, let t = 4ρ and b = 36ρ. Using Neuber’s nomograph (Figure 14.10), determine the value of Scc for the case where the bar is subjected to axial tensile load.

For the flat bar in Figure A of Table 14.3, let t = 9ρ and b = 36ρ. Using Neuber’s nomograph (Figure 14.10), determine the value of Scc for the case where the bar is subjected to axial tensile load.

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).

For the flat bar in Figure A of Table 14.3, let t = 1ρ and b = 9ρ. Using Neuber’s nomograph (Figure 14.10), determine the value of Scc for the case where the bar is subjected to axial tensile load.
