  • Crude Brass Eye derivative.... why?

  • bloody quality.

  • haha, kk...

  • .. have exactly the same friction coefficent given that they are on the same surface :)

  • Well yes, but really what I meant was that the bottom surface area of an object does not effect it's friction coeffient.

    A large metal plate and a small one have exactly the same friction coefficent, regardless of their surface area or mass.

    You could talk about surface area when you mean the roughness of the surface, but that's not the common way to look at it.

    Now naturally we would have to consider adhesion and cohesion too, but anyhow.

  • and the roughness determines how much surface area is in contact between the objects. two smooth objects gives lots of friction, as does two rough objects, as the particles are in contact constantly. a rough (or bobbly - like football boot studs) object and a smooth object together produces the least friction

  • hahah deadly!! wasn't that science expert in father ted?

  • Surface area has nothing to do with friction! Only the roughness of the two surfaces determines the friction coefficent.

  • Ha! D4 to de core!
