Here is a good bar bet question.
If two tires are inflated to the same pressure, but one is 225mm wide and the other is 195mm wide, if you install a set of each on the same car, which puts more rubber on the road?
I bet you 90% of gearheads will say the 225mm tire.
Yet the answer is neither, they will both put the same amount of rubber on the road. However, the shape of the contact patch will differ between the two. The wider tire will put a wider but short patch, while the narrower tire will have a narrower, but longer patch.
Someone use the nice convenient numbers of 6" wide by 4" long vs 4" wide and 6" long.
Fun with physics
I think I'm hanging with the physics discussion pretty good for a EE with an emphaisis on digital design.
