A thin sheet of fibreboard weighs 60 N and lies on a rooftop, as shown in the figure, where 20 = 3 m, L = 1.5 m, and b = 2.4 m. The coefficient of solid friction between the board and the roof is o = 0.1. Assume turbulent Tu 0.027 flow and consider the coefficient of friction, Cp = 0.5pU2 1. What wind velocity (in m/s) will generate enough friction to dislodge the board? 2. What is the drag force (in N) on the fibreboard when the wind speed is 20 m/s? Xo L U m/s b Fibreboard Roof
