Torque and Equilibrium of a Rod

  1. Apr 7, 2013 #1
    1. The problem statement, all variables and given/known data

    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.


    2. Relevant equations

    Conditions for equlibrium F net=0 and Torque net= 0.

    τ= r F sin θ



    3. The attempt at a solution

    Honestly I am not even sure how to get started. Please help.

    Is this a serious problem?
