multi drive shafts
Agreed. I have been thinking- I would say go look at a large dump truck. They are frequently 3 or 4 sectiond. The fact that are used under high stress situations means they are sucessful, and you can guess as opposed to running numbers.I had a college proff that could guess closer than I could calculate, that's what 40 years of expierence does. My specialty is processing light weight paper, lots more interesting than it sounds. But thats why I PREFER not to do this.I am pretty good with gas dynamics-turbos and like. .Thanks, Good observation. m PS If you want the torsion spring effect, you can put one section say 24 inches in. I keep thinking about dodge pickup front bars, I don't think they are big enough. How many ftpds, are you putting out-any body?
