CK5 just added a "Off-Road Extreme" forum to the site. That prompted me to finish making my excel spreadsheet to calculate "stuff" for 4-links.

If any of you know how to calculate this kind of "stuff" I could use some help making sure I didn't make any mistakes.

I fixed a few stupid things...it wouldn't change when you changed the wall thickness or OD of the tube:rolleyes:

BTW: The cells are protected just to keep you from accidentally screwing it up. If you really want to change the formulas you there is no password for the protection.


For those of you that care...

Assumptions:

1) Loads are calculated with 100% weight transfer.
2) Tire coeff. of friction of 1.
3) That you have 4 non-parallel links:flipoff2:
4) For the F.S. (factor of safety) in bending you have half of the weight of the truck acting on the center of the link.
5) Your links are made of steel with a yield of 63,250 psi (normalized 4130)...if you want to use a different material you will have to find the spec's and plug them in on the 2nd page
