A flat bar of a relatively brittle material has a fillet as shown in Figure 14.24. The thickness of the bar is 24 mm, ρ = 3 mm, h = 50 mm, and H = 68 mm. The bar is subjected to a static moment M. If the allowable (working) stress for the material under this condition of loading is σw = 14.0 MPa, compute the maximum allowable moment Mmax for the member. Assume that q = 0.80 (see Eq. 14.44).
