Greetings phys-eders:
I am attempting to set up an experiment similar to
what Cavendish did when he "weighed the earth".
I'm using two joint compound buckets filled with sand
as the larger masses. I have a meterstick horizontally
oriented with bottles of sand on each end. This is
suspended from the ceiling with video tape.

I'm finding that it takes an incredibly long time for
the suspended meterstick to find its equilibrium
position. Once it does, I'll move the buckets in
closer to the bottles of sand and see if I can detect
any torque on the meterstick.
My questions are:
1)Do you think the incredibly small Fg would produce
any effect?
2)Have any of you tried this before? If you did, how
did it work?
3) Any suggestions?
