I don't know if this diagram will come through but, if AB is a rigid
beam attached to a rigid post BC which is attached to a rigid beam CD
which is pivoted about the marked pivot point, what happens as an
increasing vertical downward force is applied at A? Which way does the
balance tip? What is a good, instructive, way to look at this
situation? Am I making this more complicated that it is?
Thanks for any help, David Abineri
