Can't Figure it out...............................?

Question

If the wind is blowing from the NW at 30 knots, calculate the pressure on the body of one of the campus figures facing the wind and, from this, calculate the torque on the welded feet.

Answer 1

Look at it from the other perspective; how much drag force is generated when the figure is moving through still air at 30 knots?

The drag coefficient for a man in an upright position is on the order of 1.1

To calculate the torque, you need to know how far up the figure the center of action of the wind is. I can't speak for your campus figures, but I'd use about 2/3 - 3/4 up. (The wind velocity is lower closer to the ground and most people's torso has more cross-sectional area than their legs.)
