[python] 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. The pivot is a thin ca 1.5" x 14" steel tube with nylon washers in each end. It looks very much like the pivot on a Bob Yak trailer.

Besides the fact that such a long pivot can be in the way - would it work on a python? The Jouta has a hideous negative trail (half a metre) but since the pivot is placed roughly at the same distance from the rear wheel that it would have been placed from the front wheel on a python, I think the load would be the same.

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