An angle section, with legs of unequal length has the dimensions shown in figure 2. At this cross-section there is a moment M = ?15 kN m applied at the section centroid C and this is oriented parallel to the short leg of the cross-section, as shown. Given that the centroid of the section is at ?z = 26.1 mm and y = 76.1 mm, and the principal second moments of area are I?u = 28.7×10–6 m4 and I?v = 3.08×10–6 m?4 (the principal axes and their orientation are given in figure 2), determine The stress at point A
