If you have a question about this talk, please contact Ms Helen Gardner .

It is well-known that nanoscale friction differs significantly from its macroscale counterpart. In particular published experimental investigations of friction between a single-walled carbon nanotube and a silicon dioxide substrate have shown that the force required to induce sliding over the surface is independent of its width up to approximately 230 nm. For greater widths the required force to induce sliding increases. In the current investigation we propose an explanation based upon a simple structural mechanics model.
