Welcome! Our goal is to not confuse you with excess theory, but to solve as many problems as possible while explaining every step of the way. We feel this is the best and most efficient way to learn! We currently specialize in Civil Engineering content, and general university mathematics. Please like our videos and subscribe to our channel, as well as on twitter and Facebook so we can get this free content out to as many people as possible! If you have any questions, concerns, requests for content or want to contact us for any reason, feel free to send us an email at afmatheng@gmail.com If you'd like to support us and you found our videos helpful, you can donate any amount at www.paypal.me/AFMathAndEng/10 . All proceeds go towards making more videos!
AWESOME VIDEO! p.s. your colleague is handsome :P I would love to know how are you different from a "normal civil engineer" I am doing 3rd year and have not chosen my sub major yet but I would love to know the difference of sub majors in civil engineering and from your point of view, which one is better than which and why!
When you were trying to figure out whether the system is consistent, it seems like it was circular reasoning, as you solved for values a, b, and c by equating the entries, and then you replugged in the values that you solved using the same matrix that was used to solve for the values of a, b, and c. It is going to come out as "consistent" every single time because you are just solving and then going backwards (unsolving) every time; of course you are going to get the same matrix in the end. That doesn't make sense to me.
This is dumb. Look at a simple example: 1x * / \ 1 X X is a function in parentheses (a variable). The coefficient and the variable have the same priority. They are both needed at the same time to complete the multiplication. Any coefficients (either constant or variable) have the same priority and are multiplied together with the parentheses before doing other operations. ie 2x, 3xyz, 4abcdefghijklmnop all eventually combine into the top multiplication. You can read left to right if things have the same precedence, but identify coefficients first. You have to build a tree from the bottom to the top, and you know parentheses are leaf nodes at the bottom of a branch.
Hi There! These two videos are great! Can you do an example of a strip foot design where the foundation wall sits on the outside edge? Basically the structure is right next to the property line.
I apologize if I'm asking a stupid question. I'm just unfamiliar with this topic. But how do you find the vertical support reactions at the base of the column if we have a rectangular frame like this?
By far the best, articulate video on this topic on RU-vid! Double the Thumbs up for AF Math & Engineering. BTW, I put these formulas in a spreadsheet, unfortunately, I'm not coming up with the same results as depicted in the video e.g., . I cannot make out the with of the wall. Is the width of the wall 203mm? One other thing, when I plug the numbers into the formula qf x b x ((( l - t )÷2 ) - d ), I come up with 68kN/m where you show 47kN/m. Thanks.
If the clay now is fully saturated and under water level, I need to use gamma submerged? Our prof said that we need to subtract gamma saturated with gamma water to obtain gamma submerged?? Please give me the conclusion
Very insightful video, however is there any tutorial on how to assign wind loads for circular surfaces, I feel like it gets tricky when considering the direction and since we are not defining a direction I wonder how it has to be assigned (in the form of exposure to shell elements)
