Hello, when we aere calculating Pj and Pe why you consider D infact the pressure should only be consider for the soil above the point of rotation and below the point of rotation.
Some Pa formulae I've seen is Pa = unitweight * Ka * H^2. note the H^2. I noticed you dont square your height. If we compute the units (metric) using your formula we get kN/m3 * m = kN/m^2, whereas when you square H you get kN/m3 * m2 = kN/m. Which is the correct equation to use and why would we square H? Great videos by the way, I'm starting off as a civil engineer and its good to learn off videos like this.
Thank you very much for the video.I have a question please, the pressure at any height from top is P=gama*Ka*h but at the bottom is P=(gama*Ka*h^2)/2. The only thing I can think of about the h^2 is because it's at the bottom. Is it correct? and how about the 1/2? where is it from?
The imperial system really bugs me. Great video, and thank you for it, but, could you use the same system the rest of the world uses: metric ? Thanks you.
Do you think he chooses what unit system the entire united states uses? I know mostly everyone uses metric but come on lol its just a unit conversion...
Great explanation of Earth pressure on a cantilever wall, we also build retaing walls like this.
Thank you
love ur videos....they are extremely helpful......please post more of 'em...i am a student of foundation engg
what is that 3780 psf? a constant?

I think the active pressure at ‘J’ on the excavated side is 120x(D)x0.33=40x(D) not 36.9x(D)

Brilliant Video and Powerpoint!!! is there any chance you can email that powerpoint to me?
Thanks

+WHY70122 Area of a triangle is equal to .5*base*h^2.
plz give me the link of next video ..thanx for explanations ..:)
How do you compute for d ?
Very useful to understand
thank you man :)
what about if we have seeping through soil ..is it the same case what did u teach here ??? expecting a reply ASAP
man ..... bro thank u thank u thank u

2nd lecture
got foundation exams :D
