The superintendent of a national cemetery wants to erect a larger than usual flagpole and flag. The flag pole is 125 ft tall. The flag has a height H = 20 ft and a length L = 38 ft. Assume the flag pole must withstand a wind of 60 mi/hr at 32 °F when the flag is flying. The drag coefficient of the flag can be estimated by CD = 0.05L/H (note, A = LH used in calculating CD). If the pole has a diameter of 9 in., determine:
a. the total force exerted on the pole (in lbf)
b. the moment at the base of the pole (in ft-lbf).
