updated spreadsheet for calculating FD curves

Postby jwillis » Sun Apr 11, 2010 8:44 pm

I reworked this file again today. Hopefully it is correct now! Dude, I cannot figure out what was being done in the original spreadsheet file that I was using. The data just did not come out right. I'm not sure who created that sheet but I heard that it came from Norb Mullaney. So...all of the WTT3 efficiencies were reported as being about 1-1/2% high...ugh. I rewrote this new spreadsheet to be much simpler...to calculate SE by just adding up the draw force at each inch and divide it by 12 to convert it to pounds. That seems to be what everyone wants to see. Mulaney or whoever had it doing something completely different that I don’t understand so I eliminated all of those confusing columns. I looked up the Larry Wise book on the internet that tells how to calculate all of this in real simple terms and got some data from there and plugged it into the spreadsheet to make sure it matches up...now it does. Send me a PM with your email address if you want me to send you a copy of the file. Jim

Go ahead and laugh...this is a curve from a compound...lol...but I used this data so I could check the results against the Larry Wise book... http://books.google.com/books?id=Bz6xU2 ... &q&f=false
