Estimate the torque required at the base of a flag pole to hold it in place in a 30mph wind. Assume the flag pole is a vertical cylinder with D=10cm and L=10m, and assume the wind drag force is uniform along the pole. ( if needed, use air density(p)=1.2kg/m^3, µ=1.8*10^(-5)Pa*sec; water properties:p=10^3 kg/m^3, µ=10^(-3)Pa*sec)
