Honestly, I don't even know how to begin this problem. I've drawn myself some free body diagrams, but I'm uncertain of all of them. The weight of the bar is just (0,-mg) at .9r from the pivot point. But I don't know how to calculate the weight that's perpendicular to the pivot point because there's no angles so that doesn't help me. Is there an x component to the normal force? I feel like there should be, but I don't know how to calculate it because there is no x component to the weight. This was the first of 9 problems... I did the other 8 no problem. This one though... this one blows my mind for some reason.
