Sophisticated (in this context) means you can understand
a pneumatic tire can be contrived with NO contribution
from its upper half, and that this can be made to
function on a spoked wheel assembly.
I guess I am not sophisticated because I cannot understand that
"hangs"the tire is internally sectioned.wheel/tire.
The spoked bicycle wheel/tire is no different than the auto
The axle "hangs" from the top rim via the top spokes. The rim
you?from the top sidewall of the tire.
No. The bead hangs from the top sidewall. The rim is supported from
below by the bead.
Well, well, well, Jeffrey. You didn't start out as a physicist, did
:-)great!
You might enjoy responding to the design issue of showing the
ice/snow loading capacity of a blown diaphragm roof on a circular
"pill-box" arena.
These tension roof skins can be held down by a rim, despite the air
pressure differential applied across them. The side walls pull down
on the rim to keep the roof in place, unless the snow load gets too
Wait: isn't that a bit like a tubeless tire? Oh yes!
Brian Whatcott Altus OK Eureka!
