Homework Help: Find load to create equilibrium on a bar.

  1. Nov 15, 2014 #1
    1. The problem statement, all variables and given/known data
    A 6.0 m bar is supported by a fulcrum at 3.9 m from the left end. There are loads applied to each end of the bar. The load at the left end of the bar is 468 N. What load in newton should be applied to the right end of the bar to create equilibrium?

    2. Relevant equations

    3. The attempt at a solution
    I attempted to solve the solution by using a sketch and the M=Fd equation but for some reason I cannot figure out how to create equilibrium. I know that the downward force must = upward force? I would really appreciate just a little bit of guidance and I'm sure a light will go off up there!

    Well, show us your sketch and your work with the moment equation. It might be just a simple arithmetic mistake.
