Chain tension as related to hitch to axel
Hi Nick,Thanks for the referal to your thread of the mathematical analysis of WD hitches. I had more fun studying it than sitting with the inlaws for Thanksgiving. It would be my guess that somewhere along the line you taught Mechanical Engineering. Your explanations were clear and I think understandable.
Please correct me if I am wrong but as I understand from your equations, D is in direct relationship to L. I didn't try to figure out if this was 1 to 1 and am quite sure it is not but as trailer hitch to axel length decreased the the necessary chain tension to level the truck deminished.
Sooo-- with not yet taking delivery on my 20' Safari or the Equal- I- zer hitch and it's still the Holiday I used the garbage in garbage out principle. I guestimated L at 140". T is 600# per specs. Having a F250 crew cab short bed diesel with a W similar to your TV setup I used your numbers as well as B of 33" and came up with D= 763#. A number which is not worth the time it took to type but it leads me to the conclusion that the 1000# spring bar from Equal-I-zer is a better choice than the 600# alternative. Do you see a flaw in my reasoning? Thanks, Jerry
