Today is my exam and I am studying this important topic here (thank you for helping poor students like me 😅

Good morning I am watching your videos regarding testing and I want to learn more I found your video interesting

Uhm.... So can we compute the coefficient of friction by myu = shear stress/ normal stress? I don't know if anyone would answer from 8 years ago video...

I have a groundwater midterm tomorrow. This was very helpful!

❤

Thx❤

🎉🎉❤

the effects of gravity, where are they in the formula?

Very helpful content.Please continue such amazing work.

Pretty nice explanation. Thank you.

Hello please help me.. I test disposal material. The shear stress of material keep reduce after peak, and not showing the stabel displacement after that (I mean I cannont define the residual parametes).

I still didn’t get it

👍

Wow! No one explained φ in soil mechanics like this. Big thanks

Can you recommend a document or book

Could you explain why the standard test ASTM C 29/C 29 M uses the term unit weight as bulky density? :(

The illustration is so brilliant. Very informativne! Like how you define on example of GRAUNDWATER FLOW and PERMEABILITY because it is NOT similar but is important to undersanding Darcy's Law in civil engineering. Also in few minutes you give important formula and what is HYDRAULIC GRADIENT in this case. Groundwater is simply illustrated from area of high water levels to area of low water levels - we say that groundwater flows from areas of low hydraulic head to areas of low Hydraulic gradient. It is therefore the HYDRAULIC GRADIENT which graundwater flow but if is tottaly float there would not be groundwater flow. I can conclude that you did master design fit in few minutes! As such, it is a good example of PERMEABILITY as well ~ ability to control speed og groundwater flow. It is the ability of a rock or sediment to transmit fluid and form of Darcy's low in planty hydroprojecting as well as for achiving new research.

Great vid

Ótimo

Im writing tomorrow and I just saw this now😭

Are you writing backwards?

Go go metric units!

Is slippage between the two cells/boxes accounted? Can it be measured in the test?

Hello Thanks for your lectures. One of the projects where the permeability is needed for the top 5 meters. The well is a semi penetrating unconfined aquifer, but we reach a depth of 30 m and no aquiclude has been encountered. What is the thickness of the aquifier (H) that should be used in the equation in this case? In addition, I don't understand how the thickness of the unconfined aquifier can affect the flow rate into the semi penetrating well. Assuming the well is 5 meters deep, does it make any difference in the flow into the well if the aquiclude is 10 meters or 100 meters deep

Thanks sir,well explained

Wow. This is so well explained! You actually took some time to explain coulomb friction and that led me to understand angle of friction and shear stress! Thank you SO MUCH!!

These explanations are amazing, they could get rid of most lecturers and replace them with this video.

shouldn't be K the hydraulic conductivity and not the permeability?

How does he write upside down?

Why not Mt. I got confused

Thanks a ton. So much more well explained than my study material :)

thanks for the cram help

i was so confused that how volume will increse in dense soil , and u explained it beautifully sir. thanks you 👏

Hello sir very explained video as well as presentation.....please share us introduction to your studio arrangements

What percentage of water does the sample contain for odometer test? for disturbed sample.?

Potters clay, what are we made of??

awesome thanks!

Wrong explanation. Permeability is the ability/measure to transmit the fluid through a porous medium. The unit is m2 or D.

HE WROTE BACKWARD?

what is physical and mechanical plasticity?

Very good tutorial.

u make good videos. why stopped

you write backwards??? this is bothering me

What's the W stands for?

So helpful, thank you! Studying for the PE and needed this refresher on the fundamentals.

Thanks

thanks you

Thank you.

Lime (Ca(OH)2 hidrated or pure CaO) is used to stabilize clay soils on road or building foundations. It has to be well mixed to the clay. So I guess interacts and fill that gap between the Aluminium layers in this case. But how does the so called pozzolanic reaction happens?

Thanks for your nice presentation. Do we need undisturbed sample or disturbed sample ?
