here is the question:
A uniform rod pivots about a frictionless, horizontal axle through its center. It is placed on a stand, held motionless in the position shown below, and then gently released. On the right side of the figure, draw the final, equilibrium position of the rod.
There are some online solutions showing that the rod will not moved at all as you release it, because it is already in equilibrium. However, I don't think that solution is correct. My intuition tells me that the rod will be horizontal in equilibrium, and I even conducted an experiment by hand-holding a uniform rod to verify my prediction. (As I released the tilted rod, the rod rotates and becomes horizontal) I can't come up with a good explanation on this problem. Can anyone help? Thank you!
