I am researching soil shear.
Because soil contains water, water pressure affects measurements, and there is a method called triaxial testing.
We obtain data in situ, record the data in a form that allows us to remove pore water pressure in the same way as triaxial testing, record the pressure at the time of failure, and analyze it. In that case, by comparing the data separated into rotation and load vectors with the movement of pressure, we can obtain data at the time of failure. This explanation was very helpful, and I appreciate it.

you are an absolute gun, you have turned me not understanding my 3 hour boring lecture into a 15-minute essential guide to bending. Thank you so much :)

[@ArspectuS]

You got this because this is less boring lecture💪

[@jasontien9291]

Saving me from my exam, thanks man

[@NicolásBenjamínAlonsoVillarejo]

so valuable! thanks

[@nicholasofthetube4557]

Thanks to you I passed Mechanics of Materials! Thank you so much

[@user-zw3eo1pl9p]

so good bro i better than 2hr college lecture

[@dogukanyildiz9741]

YOU are killing it, best regards :D

[@skyward7903]

Saving my degree honestly! Thank you sm

[@teachyourself7374]

You are awesome dude

[@AverageNeighbor]

Great vid, new sub

[@LessBoringLectures]

Thanks! Share with your friends!

[@WaffleSlapp]

This is amazing! A small problem for me are the imperial units. You might reach a wider audience if you use SI units but it only matters in the example

[@LessBoringLectures]

Ah! I know... I do use both types of units for the example videos. But thanks for the suggestion!

[@jasontien9291]

@@LessBoringLectures you doing amazin bro, in every engineering course they fuck with all three units, they want you to be able to work with all of them.

[@dylanslocombe9243]

does the neutral axis always run through the centroid of a cross section?

[@nahomtesfaye5315]

it is great vid but try to be calm when you tech because some of us english is not out first language so pls
