The miniaturization of mechanical devices has evolved to the point that microelectromechanical systems (MEMS) are now in widespread use. While useful nano-mechanical systems have not yet been constructed, some prototype devices with sub-micron dimensions have been made and it seems unlikely that the ultimate lower size limit of functional machines has, on the micron scale, already been reached. In this seminar I will discuss some of the issues that arise when the dimensions of a mechanical device approach the nanometer length scale. I will provide some examples from molecular dynamics simulations of simple carbon-nanotube-based mechanical systems to illustrate the host of problems that will arise in the design of deterministic nanomachines.

This talk is part of the Theory of Condensed Matter series.
