Hi All,   Just a thought...Has anyone explored a simple 36"? pendulum, =
say having a 2? second period, then containing the pendulum in a fluid.  =
The pendulum still should move from side to side, but with a longer =
period?    I have no idea, how to do this, or what the result would be.  =


I think the result would be similar to an "oil damper"....but an oil =
damper does not change the period, does it?

To ask it in a  different way......Picture the 36" vertical pendulum =
swinging in a large tube filled with air,  Now the same pendulum, but =
with the tube filled with water.
Would this change the resulting period?
