Wow! This is really difficult!
-----After seeing this post and its very close parallel to many others I decided to do a little more testing and set up our electronic load cell set ups we use to calibrate our dynamometers information gathering systems.
I didn't use it in the video as I thought it would be to difficult to see on camera and more complicated for most to understand. I immediately began to see errors consistent with some of the posts here. So! to make a long story short I decided to give up on the 5th grade math and and go to some true first year engineering school math. I truly wish I had listened to some of you in the very beginning as I could have saved myself considerable embarrassment here. The math I applied from scratch matched the little online calculators perfectly,
thus proving I was wrong in my .8 with any wrench length statement. As most of you have seen the demonstration video I made at considerable expense. I sincerely hope you guys don't think I was trying to mislead or deceive you. I really was trying to do a service, not win the debate. The small errors I picked up on, I attributed to errors of mechanism or wrench design anomalies. At any rate an apology is in order to everyone on both sides of the fence. I feel pretty stupid over this one and learned a valuable lesson. I hope I didn't cause you guys too much stress. The good side of this debate is we sure are selling a lot of products, but I assure you guys, it wasn't planned like that. I hope I haven't alienated too many of you with my hard headed attitude. I Really love this forum and and all who contribute here. Best Regards, Allan
