The wing spar ABD of a light plane is made from 2014-T6 aluminum and has a cross- sectional area of 800 mm², a height of 79 mm, and a moment of inertia about its neutral axis of 1.07(106) mª. Assume A, B, and Care pins. The neutral axis passes through the cross-section at half of its height. Connection is made along the central longitudinal axis of the spar. The anticipated loading is to be as shown. (Figure 1) Determine the absolute maximum bending stress in the spar 0.6 m 14.4 kN/m -0.9 m- B -1.8 m
