A C-channel wing spar is constructed using 4 stringers and 3 very thin skin panels. The cross-section properties of each stringer are (A = 0.4 in2, Iyy = 0.2 in4, Izz = 0.3 in4, Iyz = 0.3 in4). Calculate the C-channel cross section inertia (Iyy) for b = 3.88 inch and h = 3.68 inch. Neglect the skin. (Units: inch^4)
