was wilhelm albert really the first to discover metal fatigue? i have to imagine someone must've bent a wire back and forth until it broke before him. or is that not metal fatigue?
I'd had no idea why it is important to torque bolts to specific tightness. The preload prevents excess wiggle, which can wear out a tiny area, opening a notch for rust and disasters.
I wonder how accurate your analogy of preloaded bolts and grow not a show appendages is? Does being a grower not a show-er generally mean you will encounter fatigue faster than a preloaded stud? 🤔
Corrupt and brazen and shady developers in Toronto. Look at the city’s crap elevator companies from soup to nuts. And no one seems to investigate this pandemic of corruption. These goose steppers all buy the condos, and piss and moan in the elevators. But do they know who and where this money for these flimsy cardboard forts they call homes is going? Does anyone really buy the value ratio that is happening. Toronto is a pyramid scam. Age based. All the Boomers seem to be just fine. While voting for the developers. Gross
Something worth mentioning , that may not apply here . I work on excavators that have a rotex bearing with balls rather than rollers . Once in awhile , we got one , where the rotex bolts all snapped , and the house , fell off the car-body . Others had a lot bolts break . It was on a lot of Samsung larger excavators ,and Cat mid-sized excavators . Cat solved the problem . They put a thick steel sleeve in the system , about 3 inches long . The longer bolt could flex more in a shock load , and prevent either the bolt heads popping off , or bolts breaking at the nut-thread interface [ which rotexes dont have ] . They recalled the midsized machines in the early 2000s to put these sleeves in . They didnt break anymore .
I worked in a factory in asia for 10 years making rubber dog shit (also a spring under hookes law) How do I better myself and become an engineer?
"roscoe tried to miss him, but he didn't quite" great song reference very appropriate
I'm currently writing a research paper in my risk management class, going to loosely base it on this crane disaster video(s). Thanks AvE!!

WOW. SPANKS..
Thanks 4 splainin' the metal fatigue dance.

If the bold was not loaded and noticed then loaded a month later what should been done?
I LOVE how excited you got over wire rope. I learned something today.
insurance companies go in to tank when a crane collapses
Hey, crane accidents are serious business… This is no luffing matter!!
Something fishy with that torque pattern…

I completely agree.bolt torque. 😏❤️🇺🇸🖖🏼
Where did the steel come from?

As usual I understand about 75% of the words, but the meaning is perfectly clear. I think Websters may need an update.
