"Dave Baker" quickly quoth:

I did a "back of an envelope' calculation with
regard to the stored energy in one of these
things,and avoided them like the plague ever
since.

That's a lot less energy than an average IC engine spinning at 6k rpm so I'm
not sure what you are so frightened about.

Are you sure, Dave? The forces at such a larger radius and such a
larger mass at 300 RPM would seem to have a lot more energy than an
average IC engine could put out. (I'd like to see figures on both for
S&G. Throw in 1,500hp funny car/dragster engine figs, too, please.)

My truck's V-8 engine is spinning at an angle which would not slice
and dice me if it blew. (Although the new small cars with transverse
engines have their radial mass trajectories (what's the correct term
for this?) "aimed" more toward you, they have considerably less mass
to throw atcha.)

LJ--who doesn't recall hearing the term "centripetal" before this
newsgroup and has zero college math under his belt.
