By textbook Solutions, Xk=1.72, Xo'=2.19, new b=20.26mm but I got Xk=1.72, Xo'=2.301, b=71.2mm So I want to double check

By textbook Solutions, Xk=1.72, Xo'=2.19, new b=20.26mm
but I got Xk=1.72, Xo'=2.301, b=71.2mm
So I want to double check for my solutions
8.16 A beam with a rectangular cross section has dimensions, as defined in Fig. 8.13(a), of b = 50 and ? 1 = 10 mm. The beam is made of 7475-T7351 aluminum and is subjected to a bending moment of M = 10kN m. A through-thickness edge crack of length as large as a = 4 mm may be present. Safety factors of 2.0 against yielding and 3.5 against brittle fracture are needed. (a) Are the safety factor requirements met? (b) If not, what new beam depth b is needed, assuming that I and the other values given remain unchanged?
