Sir I have a question what if the second layer is clay is it a must to always follow the condition which is use the half of it's heights as a multiplier to get the effective stress and for total stress?

[@xabierjimenezbilbao7545]

In this video 5 "Worked Examples" the effective stress is calculated with the density of saturated soil (16kN/m3) instead of the one for the submerged soil (5kN/m3=15-10).
Why is that? Is this an error? or is there any justification (which I can not see) to adopt the saturated density instead of the submerged density? Referencing to Video 3 "The Fundamental Building Blocks" the one which should be adopted is the submerged density, isn´t it?
Thanks any way for the so clear and interesting videos!!! GREAT!!!!!!

[@DarienCharlton]

Great explanation however, it should be noted the unit weight of water is 9.81 kN/m^3 not 10. 10 makes it easier for quick ballpark estimates.

Very clear and informative explanation. Great study aid for Soil Mechanics

What if there is capillary rise ??

[@aroshisenanayake7279]

We are reducing pore water pressure.why did u reduce the water pressure above soil layer from toal stress?

You are simply amazing. Wow
So nicely explained. Thanks a lot

[@MasterCivilEngineering]

Yes

[@upendarsharma1490]

hw it got 218.5 in no change problem it must be 198.5 as the previous one.

this video is very helpful to engineering students

The music was driving me insane
It's literally an 11 second loop
