Using the jack as a press is such an elegant solution. I love simple, effective engineering.

This is a super video that every Civil Engineering Lecturer should watch with students in class to get a better perspective to design and imagine before what they will work on.. Thank you man !

I have no clue why I clicked on this, but I watched until the end

Also, it's worth noting that concrete and steel have very similar coefficients of thermal expansion. That's what makes steel reinforced concrete possible.

Illustration made here is INSANE. BRAVO! 👍👏
@nabedesu7708
Im a civil engineering student and came across your video randomly and id say watching here actually helps me a lot in understanding the world of civil engineering. There is less civil engineering based channel so this kind of channel is a gem to me

When I was in engineering school the class went to a company that made prestressed concrete I-Beams. It was fun to jump up and down on the top of a 100 ft I-Beam and get it into “resonance”. It is amazing how flexible they are.

The best visual I have seen regarding the principles of pretensioned concrete.
@CodeOptimism
I've seen multiple videos on concrete in compression/tension and this is the first that explained it extremely well. Most talk about the concepts but don't really show the relevance of the placement of the rebar (other than showing it's "in there"). Nor do they have an excellent simplified example like yours with the reinforcement clearly on the bottom in a simple case with gravity... with a follow-up showing a building and how the tensile forces can actually be at the top, etc. I thought this was excellent.
@happy__human
Great video sir Thank you for explaining so interestingly
@aye2036
Amazing illustration!! Really impressive. Never stop making engineering a little fun to understand. It really helps tons of students out there. Sending prayers!!
@pawanshetty5019
Your videos are truly amazing, sir. Your explanations of concepts in a simple manner are excellent. ❤❤

Hi Professor, I’ve been watching your content since the early Learn Engineering days. Concrete being weak in tension is a topic that is covered frequently already. A couple things I think you could add that would make your video go beyond than the rest and really be enlightening would be: 1) Compare a reinforced concrete beam’s load capacity to that of just the rebar, (and/or unreinforced concrete plus bare rebar) 2) visualize in a column that rebar stirrups and main bars resist against the induced principal shear and/or effective radial tension. (You could show the different common failure modes for unreinforced standard concrete cylinder samples; how they usually fail on a single shear plane or sometimes conical surfaces.) 3) Bonus #3 would be how concrete isn’t really as good as steel in terms of physical parameters, but in the practical world it complements steel by being much cheaper by volume and weight, and leas dense, which allows you to use much larger cross sections (and larger dimensions benefits beams and long columns exponentially); the concrete protects the rebar from Corrosion, concrete holds the steel in place and somewhat combines them into a single body (compared to how before the concrete the rebar was just tied together with wires); the concrete can be installed as complicated geometry in large volumes economically because it’s a liquid* you pour into forms and around rebar (compared to having to fabricate, transport, and erect an equivalent structure or floor area out of steel, pumps are very practical)

I am always super surprised by the depth of such a "simple topic" of things we see in our every day life. Thanks for putting this videos together! Mostly I love the "mad lab" parts with the dedication to take the ceiling apart, just to hang a rope to show what happens.
@briankenison7995
I hate to say it but I've been a rod buster for 30 years. I'm still amazed with everything I build. Built a bridge in Vermont with fiberglass rebar. Best job of my life. 😊
@Jakh-k6y
You do the best visualization videos and explain things in detail
@TheEdrt
As always, beautiful content with real life example. Thank you very much, you can not even imagine how useful your video's are for students everywhere in the world. Greatings from Italy 🇮🇹
@haroldwood1394
Excellent video! I am going to use it to help my students to understand ideas about load-bearing structures which they previously had trouble with.
@justgivemethetruth
Great demonstration of tension and compression. Excellent video.
