sign illustrated in the figure is subjected to a wind velocity of 72 kph perpendicular to its frontal area. There is a perfect connection between the smooth cylindrical pole and the rectangular board. The density of air is 1.2 kg/m3 and its kinematic viscosity is 10-5 m2 /s. Using the accompanying figures calculate the following: a) the drag force on the rectangular board b) the drag force on the cylindrical pole c) the bending moment at the base of the sign
