I have a question about a stress simulation that i'm doing for a school project. I am now simulating a steering shaft but the problem is that the results are really unrealistic. I apply a tork to my model of 50 Nm (which I think isn't that much for a quad steering shaft) and my minimum value of safety is far beneath one. I hope some one can see what's wrong with my model because I can't seem to find the solution.
PS: The file was to big to upload, so here is a dropbox link: Dropbox - Steering shaft.zip
