A television transmitting antenna is placed on top of a mast which is 30m high and 300mm in diameter. The mast is on top of a tall building. The wind blows at 35m/s and at normal atmospheric pressure (1.225kg/m^3). If the drag coefficient for the mast is 0.2. calculate: (i) the total drag force on the mast. (ii) the bending moment at the base of the mast. (i) Fd=.5*Cd*ρ*U^2*A=.5*.2*1.225*35^2*(30*0.3)=1350.6N (ii) but how do you do this question? (the answer is M=20.26kNm but i do not know how to get there) thank you in advance for your help.
