    Bro, isn't there something wrong? I put 3250 under my bed every month so in 36 months I accumulate 117000$ without even interest. You calculated less money with an interest added. It seems like you invented negative interest before the bankers of Switzerland 🤣 just kidding.. can anyone explain the logic?

  • @TheRakin111
    @TheRakin111 Před 2 lety

    I'm confused why for PE we are calculating active and passive pressure at the bottom of the sheet pile when in reality, we should do it at the point of rotation. Any justification for this assumption?

    • @unkind4ever
      @unkind4ever Před dnem

      i struggle tu understand that aswell; the formula for PE only holds if instead of D he would have (D-z), where z is the distance between the point of rotation and the tip of the wall; and same for PJ, why does he consider to have passive pressure over the depth D, when in reality the passive pressure is acting only on the "z" distance, while the active pressure is (h+D-z)

    Those saying he doesnt know what he's doing are either highly ambidextrous or too dumb to gaf. Kind of related- had a project manager come out to help us start forming the foundation walls for a bldg addition ( 3 sided foundation)...dude started at a corner, lol, stuck the horizontal wedges thru the forms then proceeded to put the vertical cinch wedges in upside down (from the bottom up)...I walked over and smacked one wedge with my hammer and of course it fell right out.

    l am one of the Victims. At first, the software seemed to be really professional and authentic I found many favorable reviews about its performance and delivered results. So, I decided to invest in it and try to achieve success in the online trading sphere. Soon, I realized that the software was swallowing all my investments. Brokers are nothing more than a dangerous and fraudulent platform. I invested over $ 140,000 and couldn't withdraw my money, months passed and still nothing So, I reached out to Peter Harold to help me recover my funds, I have been able to recover $ 100,000 and the remaining $ 40,000 is in progress.

  • @TheAncientColossus
    @TheAncientColossus Před 3 lety

    Is it always safe to assume that the slope from B to the point of rotation will always go towards the excavated side, i.e, passive is always greater than active? Even though we can have a large depth of active pressure? Edit : 4:41 Partially answered my question but I still have doubts about the rate of change and the direction it is going.
