- What is the force of a wall on a revolvable rod?

- Relevant Equations
- II. Newton Law, Free-Body Diagram

I have a dilemma.

If I look at the diagram and say the sum of the forces in x and y direction has to be zero, then I will simply conclude that the force of a wall on a revolvable rod is the blue N as drawn.

But what if the force is actually the green N? To me, it makes more sense because if imagine no tension and no mass M, then the force of a wall N would be drawn as below (green N).

So how can I argue that the orange component of N does exist? If it exists...
