Wow!
This was great!
Brian, F=mewstatic * Normal Force to yank the trailer, then lowers to mewkinetic once it's moving. Except for motorman's initial pull out of the field, the load on the hitch/frame interface was pretty close to advertised limits in raw numbers. Of course, the same can be said with the correct rated load, so it still is probably a tad too much shear in the hitch pin and attachment bolts with the mobile corn bin.
For the overloaded airplane analogy, I'll ride on the plane for the extra runway it takes to get airborne but I'll jump out before you try to land it. Kinda like the same reason a large plane has to dump fuel on a turnaround - the landing gear typically won't like the fuel weight, (or overloaded weight in this case), as you hit the runway at anything over one "g" or two.
As for Dodge's designs compared to bridges, both should be designed for "forseeable misuses. " Any lawyers here, or professional witnesses should know that term. The bridge may not have an SF of 5 like I used to use in military stuff but Dodge engineers certainly have to anticipate the load on the truck at max gcwr/gvwr or whatever to experience an unexpected 2-3g acceleration or deceleration which needs to be harnessed by the truck and still remain in control. So if you are pulling your fiver of 18K, Dodge has probably anticipated you might encounter a short duration 54K event. Hmmmm.....
No flames intended. Not every engineer is blessed with good "engineering judgement" and not every farmer is blessed with an excess of common sense. I work with farmers smart enough to be engineers and live where farming is prevalent. And the next time one of them farmers burns his bluegrass field and fills my house with smoke, I'm gonna drive my red Cummins over to his place and tip over his Versatile! :-laf
