Question
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 C' are 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.
