I am a bit stuck with the attached simple model. I have a rigid circle and a beam rigidly welded to it at one of the quadrant points. I am pulling on the free end of the beam with some known force. I am curious by how much the circle will rotate (because my force is also exerting an effective torque on the circle relative to its center). The center is held in place via a spring foundation which should stretch by a known amount since I put in a known pulling force and a known spring constant but there are no rotational restrictions on the circle except general force balance, i.e. no torsional springs or anything like that. Despite the simplicity of the model, it refuses to converge which tells me I am missing something. Any help would be appreciated.
