Let's clear this up first. There is no change in a.

Right. I meant change in (a - x). Thanks for correcting.

I will read the rest of your post more carefully and reply later. But
Robert Israel kindly ran a numerical calculation in Maple and posted
the result at sci.math

http://groups.google.com/group/sci.math/browse_thread/thread/a6ee2f782df09625/b7c6fa8ac229cde5?hl=en#b7c6fa8ac229cde5

Can you take a look at that thread? I see that in your paper you
computed damping by way of your curve fitting program. Do you think
there is a way to compute the damping coefficient for the original
Cavendish experiment data? It would be great to compare linear
equation you used and the non-linear solution and see if there is a
difference.

Judging from the Maple graph, it looks very close to linear motion but
there may be a difference if we can compare the numbers for each
solution.

There is also a discrepency in the result. My calculation from the
original experiment shows a value for theta 200 times greater than
what Maple gave as computed by Robert Israel.

I would appreciate your comments on this. Thanks again.
