Good afternoon, I hope someone could help me with this problem, it is killing my head. I have an aerogenerator, I already find the torque excerted by the air (75.8N) and the force transmitted by the gear (1010.6N). The problem comes when I try to draw the free body diagram to find the reaction force (I uploaded the real picture of the aerogenerator so that you can see how it is supported. Also I uploaded my attemp of solution.
I think it is only supported by one support (Point C).
The Attempt at a Solution
Since I only have the downward force (1010.6N), the reaction in C will be 1010.6N.
When I draw the flector diagram, it seems that I am forgetting a force or moment in somewhere. I am currently thinkink that I must include a moment reaction in the support C. Or maybe, I must add a force reaction just in the propeller (I meant, maybe I have to add a unknown force in point A)
What do you think it is the problem? Because the diagram flector must close.
note: I am only making the FBD of the shaft 1
