Do you know where I could find a free body diagram for a door with hinges? I don't understand why my doors are trying to close themselves. I think something is not level, but I don't understand the hinges though to draw a diagram myself.

In an ideal situation everything is level in all directions.
Not sure if this is any clearer, but the door will close itself if the bottom hinge is offset from the top in the direction the door opens. Picture the angle of the bottom of the door when it is open 90 degrees and it might be easier to visualize why it falls shut.
