Homework Statement



Here's a diagram of a rod that's free to pivot about the point indicated. Is it possible to make the right end of the rod push down, by pulling on the left end of the rod? If so, show on the diagram the direction that you would pull on the left end of the rod, and explain your reasoning. If not, explain why not.

Please see my attachment for the rod diagram.
