[python] Re: pivot again

Take a look at the Jouta trike:

except its resemblance to the python this centre steered trike  features a
very simple pivot without any bearings.


Hej Olaf,

I would call the Jouta a rear wheel steered trike, because the
seat is attached to the front.

Can someone explain the relationship between the distance between the
bearings/bushings in a pivot and the amount of radial load it can take?


Jürgen Maier once explained this to me, but I can hardly recall it.
Instead I use a framework calculating program like fachwerk.java

http://fachwerk.berlios.de/index.html

which gives me the loads (see attachment). If you can give me
the coordinates I can calculate the loads for you.

Basically I would give nylon bushings a try, but they should be
perfectly sealed.

Cheers,
Jürgen.
