Consider, for example, the classical mechanics of an object attached to the end of a xed spring. Chapter 6 also demonstrates that thermodynamics is a straightforward consequence of quantum mechanics and that we no longer need to derive the laws of thermodynamics through the traditional, rather subtle, arguments about heat engines. As such, they borrow heavily from various resources in current literature.
This document was written because of the recognition that with current emphasis on nanotechnology, quantum mechanics is becoming increasingly essential to mechanical engineering.
