Back it off, sister. I mean, put it at the end of the track. You can
also get the manual online from PASCO, at the catalog listing for this
part.

I agree, though, the thing tends to get stuck on other hardware. And when
I load it with strongly stretched springs the motion is no longer
harmonic; it slows appreciably on the stretching part of the cycle, and
races ahead on the unstretching part. There's probably no way around this
with a motor driving a crack arm, but maybe there's another way to achieve
the same reciprocal motion.

Hey, guys. Has anyone mounted PASCO's Harmonic Oscillator (ME-8750) to the
Dynamics Track? Either I'm missing something or there's no physical way to
have the rotating arm clear the track surface.
