Loads direction on tower top

[beg1ner]

Hi all

I can't get why aerodynamic load My on tower top in load case Nr.2 is with minus symbol? Wind blows in X direction. I understand that those extreme loads is from simulation, but I'm interested how it could be? Hope I wrote understandable. I have to design offshore turbine support structure, but I have little knowledge about blades aerodynamic response. Looking forward.

Is this a followup to your earlier question (thread507-291099)?

If so, it might be better posted over in the Structural forum (forum507 ).

It is not followup to my earlier question. This is question about aerodynamic response of wind turbines head.
