Why do we always use beams which have a cross-sectional shape of I, in constructions? Let's explore this intuitively in this video Created by Mahesh Shenoy
“so there is no resistance in the center, no stress in the center, why we want to put material on the center”, this is the reason why we create "I" beam. It is wonderful explanation
but as we know the thickness of steel is higher than square tube.. and it becomes heavier than square tube.. and we get an another issue "torsion and buckling" to resist than we had to add stiffeners and braces means more material more weight and more manual labor work... so practically rectangular and square tube structures are better than i beams but just because of workability and easy manufacturing I beams are used.
The steel section that you display (at 0:08) in the centre of your first compound photograph is not an 'I'-beam. In fact it is not a 'beam' at all! It is a section of Universal Column, specifically designed to take load when placed vertically. You can see this by the fact that its width is similar to its height. A section of Universal Beam (clearly shown at the top left of your photograph) is deeper in height than width. This is because it is designed to be used horizontally (as a beam). Remember: beams are for horizontal use; columns are for vertical use. It is unsafe to confuse the two.
Why can't we use hourglass beam like as he said the compression and tension gradually increases all the way to top so wouldn't it be better to make this way to ensure a bit more safety? Can you help explaining that?
This is a great explanation video describing the practicity and forces involved with a well delivered example. Thank you! A great way to complement it afterwards, with a more math based approach, is to introduce the concept of second moment of area.

you are like the i-Beam,
AWESOME!!
God bless you ❤️
This is the top kind of stuff most of the colleges doesn't teach .... very good 👍🏻😊
This is for 11th class not College 😂
Astounding class..awsome🤗👍👍👏👏

Thanku so much I was trying so hard to understand it😭😭😭
Osm video
Man!! The explanation so simple and interesting.. Great job 💯💯
wow
Really u r a miracle

thanks
great hommage video to the I beam. thx
Amazinggg
Well exply
Sir can you please make videos on civil engineering subjects
Cost is why we use I beams
Best explaination
In Germany we call them "H-Träger" or "Doppel T Träger" (H Beam) or (Double T Beam)
And you sir, are awesome!
Nice explanation and presentation thank you
Great 🎉🎉🎉
Gr8 lecture
For a particular load which is better? I beam or channel?
Other videos showed an I beam is more rigid than C channel of the same weight
👌👌
a great video, nice job
Nice👌
Thanks a lot for this. It was of great help.
This helped me a lot to understand...thankyou sir☺️👏
Very nice
Thanks brother....
Wonderful explanation
😂❤❤❤ thanks a lot
This is a "H-beam" not an "I-beam"
Both names are used
Some call it a wide flanged I beam
its not thikker its wider.
Please Sir video hindi main dijiega
👍👍👍
can you do a video without repeating the same word over and over again, thankyou
H beam😂
