Tensile

Don, your piston speed program calculates tensile stress on the rod. How accurate is that? If i was going to have a finite element analysis done on a connecting rod would i be able to use that number with confidence?

Thanks

It's been a long time since I worked on that software. You should check it against others. Sounds like you're getting trick. Care to explain?

I'm not sure if i should say right now. As far as comparing with others, do you know the names of any other programs that will calculate it?

Sorry, I haven't used any other software. Maybe someone on the board can help?

-Allans old MS-DOS "Engine Expert" was the first reasonably priced racing engine program available to the public back it the mid/late 80's.
-One of it's features is the printout page that shows everything in one degree increments of piston travel.
-That program is currently about $500 but it has the information and you can change the weights and the rpm around to see what the load differences are.
-Allan's phone should be 1-303-238-2414 unless the area code has changed.

The gas loads can make it different in reality but should reduce it more than anything else.
