So: delta-V = ln( initial mass / final mass) * SI * 32.2 ft/sec^2 (What do you think they are? Rocket scientists?) And I have been told that engineers working in the metric system use the kilogram, not the newton, as a unit of weight, and a unit of mass equal to 9.8 kilograms. Go to your hardware store and ask to buy a rope with a load-bearing strength rated in newtons. All terracentric thinking. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
