Joooooj sta volim ove koji kenjaju i tvrde da sa uzom gumom imaju bolji grip jer misle da su upili svo znanje svijeta. I to na suhom.
Nije tu tak "jednostavna" fizika.
Kako mi se ne da pisat u ovo doba, kratki Google search je otkrio neke stvari.
Citiraj:
In terms of simple physics F = V mu... If you double the contact area, then the pressure will halve (per mm2) so the friction per mm2 will halve. However, you have twice the area of contact patch so that cancels out the halved pressure. The conclusion is that basic friction is independent of area, it only needs vertical load and a co-coefficient. You can do whatever you want with the area from a stiletto to a surfboard, the friction force will be the same.
However life is more complex than simple physics. The most obvious point is that tyre rubber is adhesive, so if you double the area you double the amount of adhesion (gross approximation). So wide tyres do have more grip than thin tyres.
Another point is that the stiletto will dig into the surface causing interlock but that is also ignored in F = V mu

Pa dajte malo mozak lupnite, da fakat grip ne ovisi o sirini gume svi bi se vozili na onima sirine biciklistickih.
