I appreciate the needle formation on each cement particle which entangle with other particle giving solid mass of strength

Nice to see hydration product like needles entangled in aggregate of cement and gravel that locks the products giving strength

Is it okay to use gravel instead of aggregates? What's the difference in terms of strength?

Good test

I’m Wondering why the centre is weak than other parts?

i just saw your video, can you tell me what type of longitudinal rebar you use, cause it seem the rebars are twisted. Thanks

So, the "carbon footprint" propaganda has reached here too? And I thought this video was supposed to be purely scientific. ;) Nevertheless, a good video serie. Thanks. :)

Bffsst❤❤❤❤❤

Really nice video. I’ve watched his TEDx talk, which was equally enjoyable. Earlier in my career I built a lot of bridges. I think was guilty of focussing too much on the technical aspects of the design, ignoring the broader aesthetic and social aspects of bridges. I never tire of Mr Firth’s talks on bridges.

which microscope type is most used investigate crack healing?

Brilliant series. Thank you.

Can someone tell me how stirrup will resist shear failure? I think The bottom and top reinforcement bars of beam will resist the shear forces I don't understand how stirrups will resist shear forces as shear forces apply in vertical direction and also stirrups is in upward position so how it will resist?

el columpio inicia arriba y la parte de enmedio va abajo. en fin que me importa

I dont think this is a typical shear failure. It seems like there is an compression arch developed and rebar acts as a tie but at some point the bond is disrupted and the compression arch collapses. I would not qualify this as typical shear failure rather than bond failure.

It hurts to watch you use a trowel.

That wasn't similar, there was a little bit of permanent strain happened.

this result in solidworks simulation is the same but 0.76 mm of thickness

Nice

What about bilateral contortional yielding?!

Thank you so much! finally understand why under-reinforced concrete is a desirable design for beam

Thank you so much!!!!

Great video, well presented, good information!

And follow with various woods / plywoods in tension

Beautiful Series

What this shows is how amazing wood is in tensile strength. The failure here isn’t because of the tensile strength of spruce being exceeded but because of splitting due to the wedging action of the bolt shank. Nevertheless the video title is accurate-it’s failure due to a tensile load.

Calculating from this video: 1.47 kg/mm2 is the failure load for wood when loaded in this fashion, useful to know for DIY.

Great video. Thanks!

very well explained thankyousomuch 💖

excellent .

really enjoying it

the content is amazing

Awesome.

Thank you for sharing... clamp force matters and also moisture content of area of wood would be good data to process... Excessive clamp force in these bolts could result in this fracture pattern.

In wood tensile strength is much heighr than compressive strength? how it is possible??

I am very dissatisfied with this video as it does not show the full break of the wood beam. Great information in regards to compression forces on wood beams..... but come on man, don't string me around. I WANT TO SEE THAT SUCKER BREAK.

Se puede traducir al español?

very useful

Nice+++++++++++++++++++++++

how is the micro-structure inspection done , i mean the steps of the process ??

Hats off sir!

Good job sir because of your vlog tutorial I got some knowledge from you

Professor ,what determines the Direction coloumn is going to buckle towards. Say there is equal chance of being buckled towards right or left as area moment of inertia of cross section is same towards the directions Please answer me Sir?

I want to be student one day there

God dam! Best
