What can scaling laws tell us about nanomachines? — Wed, 14 Oct 2009 19:37:49 +0000

[...] A caveat: These scaling laws for mechanical systems apply in the presence of internal friction (an L2 force), but not in the presence of viscous drag from a surrounding medium, which scales as L1, and with less accuracy. The scaling laws that involve both speed and force are therefore of interest primarily in systems that are far from the biomimetic end of the spectrum of technologies that I’ve discussed in many other posts (for example, here and here).
