Knowing that a beam of the cross section shown is bent about a horizontal axis and that the bending moment is 12 kN.m, determine; (a) The stress at point A. (b) The stress at point B. (c) The radius of curvature of the beam when E = 69 GPa. 100 mm M Knowing that a beam of the cross section shown is bent about a horizontal axis and that the bending moment is 12 kN.m, determine; (a) The stress at point A.
