Q8) Use a system with a single degree of freedom to determine the fundamental natural frequency of the aircraft wing shown in Figure 8. If the average cross-section of the wing can be idealized as a hollow box 300 mm x 2000 mm with 2 mm thickness, as shown, and the wing is considered to be fixed to the fuselage at one end and free at the other, use E = 70 GPa and density = 2770 kg/m. 300 mm 2000 mm 10 m Figure 8
