The wing shown in Fig. 8.60 pitching and plunging with \(3 \mathrm{~Hz}\) in a free stream of \(15 \mathrm{~m} / \mathrm{s}\). Using the strip theory, obtain the total lift and the propulsive force coefficients change by time. The wing is undergoing a motion having the dihedral angle \(h=y \sin \Gamma\), starting from the end of the rigid part with maximum of \(\Gamma=20^{\circ}\). The phase difference between the plunge and the pitch is \(90^{\circ}\), and the average pitch angle is \(6^{\circ}\). (Use 10 equally spaced strips for the strip theory).
