I am really surprised this didn't kick up

Lots of experience talking here.Wonder how many guys have welded as an occupation...and how many have picked up one end of a long piece of square tubing?Mild steel is soft and Even 10 gauge will bend quite easily.The design or geometry is very important and as i stated earlier a triangle or gusset can be very strong.

Yeah metal flexes, they covered that in a couple of my materials science classes. Oh, and a couple of my structural engineering classes. And, oh yeah, I noticed it when I was involved with doing the FEA and when I did all the TIG welding for the FSAE projects I was a part of too.

You want to really notice it? Climb to the top of a 100' aerial ladder on a fire truck and see how much you're swaying around in the breeze at the top. Like a foot this way, a foot that way. Doesn't give you a warm fuzzy feeling, but the materials allow it. You don't have to weld as an occupation to understand what you're talking about.

Local Humor. Fresh out of high school, one step ahead of the police, I joined the USAF and spent 4 years working on mostly B-52's and its fair to say I have a great love for that aircraft. After the USAF I went to college and in what can only be described as strange twist of fate I wound up back in the Navy flying F-4s at the end of Viet Nam. I tell you this only because some truths were told to me, one of which is "beware of the clouds, mountains hide in them". The other one that I remember, when I'm down in the dumps and things aren't necessarily going my way, said by my RIO who was fond of saying (while on deck or land) "it ain't all that bad no-one's trying to kill us today". Kinda puts it in perspective don't ya think! And shoot, look at the pictures of the dart if you need more proof!

Isn't that the truth!!!

My old man was a machinist's mate on the USS Forrestal, he went out on it after it returned to service from the McCain incident. He worked on F4's primarily. Got in some trouble because he had a few pilot's that would come to him and ask him to overclock the engines. Basically he would increase the fuel output to the turbines, allowing them to come closer to overspeed. Great for that little boost to make a difference outrunning a SAM. Not so great when the pilot would peg all the G-meters in the F4 and require a full overhaul of both engines.

Out of my dodge charger book. This is advertising circa 1966 on chrysler unibody design. This is what they were going for. Was adequate for the time, but not anymore with modern drivelines, suspensions and tires. This is why subframe connectors improve upon what's already there. Contrary to Uncle Tony, Chrysler was actually trying to eliminate flex. I hope it's not too blurry to read. Watching his video the other day, I just shook my head and muttered ID10T.

It's all relative right?
