Reply #56: Good point.

(...) item #2 on page #7 says that if there were melted steel in the debris pile "the heat would quickly transfer through the steel components in the excavator and there would be concern for it's operator."

This seems to confirm the 'heat sink" hypothesis of Dr. Jones (as well as my cook ware) which has been debated on other threads in this forum.

This is an error that vitiates this particular argument of the article. Congratulation for spotting it. So, either Jones, the author of this article, and yourself were in error on this point, or the Fourier heat equation and/or the widely referenced heat conductivity coefficient of steel are in error.

My guess is that the author of this article (and Jones and yourself) have been lousy in this matter.
