Can somebody help me on this problem?
 

In the pic attached, there is a solid tube in wind field. Suppose one end of the tube is clamped, I want to evaluate the torque generated by the tube on the clamping point. Could anyone tell me how to solve this problem or at least suggest some method to solve it? (does it need CFD?)

Thank you all!
