2.) The following aluminum (E = 10 x 10 1b/in) J-stringer is being used in many different commercial aircraft fuselage structures. The stringer cross-section is presented. 0.25 in a.) Calculate the section properties (A, Iyya, Izza, Iyza) about the present arbitrary axes (Vanza). b.) Locate the section centroid and define a set of axes (y,z) that passes through the centroid, where the (y,z) axes are parallel to the arbitrary axes (Va za). Calculate the section properties (A, Iyy, Izz, Iyz) in the new centroidal axes (y,z). 0.5 in .0.75 in 0.25 in Y'a 0.25 in 0.75 in
