Re: transfer of momentum

That's why I wrote "may".  I should have written some.  My very old (ca.
1960) bug 's  meter's pointer, when not moving, was sl. above the pin;
reversing, it moved to the pin.  I replaced the cable once and repaired
(lubed) the meter several times.  If I remember correctly the connection
was well after the transmission.  It's possible a connection was
ratched, but it had to be where one screwed the cable into the axle.
