I hope ADK, who posted a question a few days ago on an interesting design
problem involving reduction gearing and a driveshaft got some insight from
the various postings.

The subject of torsional vibration quickly cam up and there was a lot of
stuff mentioned, but not really a simple and understandable explanation of
the forces at work.

snipped out the juicy part

So these examples show that it can be done, but you will have to put your
thinking cap on and study up on those engineering texts.

Fabulous piece of work, Gordon.

Very well written, understandable, and agrees with what I think I understand of
the subject.

There is a difference between being able to understand the subject matter and
being able to explain it well.

I think you've done both here.

Don't know what more to add to that.
