Excellent demonstrations. I would add that "I" beams are shaped that way to concentrate the material away from the neutral plane. It was a mystery to me why construction beams were shaped that way until I learned about this principle.
Engineering is so sick, the way the torsional load and sheer and tension are so calculated and with not too much difficulty, makes the real world feel like mine craft.
I have worked in the software "engineering" space for a while. Being able to touch and feel physical material and product seems much more fun. The demo is absolutely great. I hope I had got a teacher like him.
It makes very much sense. The key is (especially in complicated structures) to understand the loads. Once you understand the loads, you can design the structure to accommodate these loads. And if you are restricted in any way in creating a stiffer/stronger structure (in for example space, as the truss takes up significant space), only then look at achieving desired stiffness/strength through material stiffness/strength as opposed to structural stiffness/strength. I suppose now in these modern times FEA techniques help a lot with this, as you can already design and test parts with loads without needing to spend the money and it might not working out or being insufficent. Especially useful for students, as it can give direct feedback on whether the train of thought is correct or not.
Its not only about the number of atoms aligned in the direction loading, but also about the average distance of the material from the neautral axis. Hence Second Moment of Area.
The chain and rope both have high stiffness in direction of high strength thus in direction of rope. And low stiffness and strength in the tangential directions. So I don't think this example really explains the difference
I was sincerely impressed when he didn't ate the chip. Damn cyborg, he's so freakin good at teaching!

Same here, man. I can't tell you how nice it is to learn something physical after a long time
loving this series and learning a lot.
why didnt he eat the pringle thoe??
Because he didn't brushed that morning
same question :)
Coz he is rather interested in clearing the concept.
Single minded focus. Food is not important. Only race car.
5 years and this is still unanswered, despite tries.

Triangles are an Engineers Best Friend
i loved the demo
Brilliant demonstration
this profsser is incredible
Thank you!. You really helped my rigidity issue.
Amazing lecture
i wish i had teacher like him
Very impressive
very good. thank you
freaking awesome! thank you :)
This is so useful, thanks! Can someone point out a software that simulates these things (if there is one), thanks.
This guy looks like the engineering version of Grumpy Cat!
i like this teaching way!
Brilliant!
excellent
I am enlightened
Impressed😁
But let's say you need the tube design, not the rectangular design, could you just use two tubes of steel side by side to reduce the flex?
THE EFFICIENT ENGINEER. You are welcome! :)
So what is the difference between toughness and strength?
The chain and rope both have high stiffness in direction of high strength thus in direction of rope. And low stiffness and strength in the tangential directions. So I don't think this example really explains the difference
6:02 there's no way he just said it steel gives in
man I steel hear it
it was so f...... clear how this dude explains, just soaked it like a sponge
