Default MA3 rim failure, where to now

A bicycle wheel does not support a
load by elongation of the spokes- exactly the opposite, in fact. The
wheel "stands" on the spokes between the hub and the ground, rather
than hanging from the top of the rim as your model would require.


Whoop! Whoop! Flamewar Alert!


Yeah, yeah, spotted it.

This must be why spokes have that significant shoulder for the rim to
sit on - otherwise when the wheel 'stood' on the spoke the nipple
would just slide into the rim tape. It also explains why spokes have
to be thicker in the middle than at the ends, as on cart wheels, so
they won't distort out of column under compression loads.

I'm always impressed by the levels of mathematics, physics and
engineering taught in US colleges. They're so, uhhhmmm, _differently_
educated over there.

WARNING: may contain traces of irony.


Traces, yes, but not enough, surely, to undermine the wholesome and
holy righteousness of American True Knowledge. Far be it from me to
describe anyone as 'wrong'.
