Re: sreering



Just a thought - might not help.

Imagine getting down on all fours - like you were giving a small child a
'horsey' ride. suppose you are going forward and want to change
direction. Wouldn't you move your hands in a 'hand-over-hand' sideways
motion? This seems similar to what the knobs on the tread of the tire
are doing.

How should a physicist explain steering a tricycle when
both legs are in the air? Or, more specifically, how to
understand that the centripetal force "comes from quasi-
static rolling friction?" In my mind rolling friction is totally
different from static friction.
