10- A publicity signboard for parliament election campaign (0.5 m wide, 2m long) is exposed to the air that flows with a uniform velocity of 4 m/s(p=1.2 kg/m³, v=1.71x105 m²/s). The signboard is mounted on a square rod (8 cm x 8cm cross-section, 2 m long) as shown in Fig. (7). Estimate the bending moment at the root of the rod due to aerodynamic Forces for the following cases: (i) The air flows normal to the signboard, (ii) The air flows parallel to the signboard. 2 m 0.5 m 2 m Signboard Square rod (8 cm x 8 cm) Root of the rod Figure (7)
