For Problem 18: Shortcut using TI-36x Pro. Press 2nd stat-reg/distr NormalCDF mu=4400, sigma=200, lower bound=4000, Upperbound=1E99 ans=0.977==0.98 if the question asked less than 4000psi "Probability(x
For Question #8 you can go to page 39 where area of parabola is listed. With this you can split the shape into the 8x6 = 48 m^2 rectangle and create a parabolic shape where the [ A = (2*b*h)/3 ] and b = 8 and h = 6 where A = 32 m^2. Using these two areas you also get 80m^2 which was much faster and easier.
Solivng question #20 using the TI-36X Pro calculator: Press 2nd stat-reg/distr. Go-to DISTR tab. Select #5 for Binomialcdf. Input: x = Single | Trials = 5 | P(Success) = 60% or 0.6 | x = 3 Select Calc. You'll get 0.66304 (the same value as from the table shown in the video. Take 1-0.66304 = 0.33696 or ~34%.
This would be amazing to know how to use, just 2 questions: Where did you get x=3? What is the difference between the options 4. & 5. under the DISTR tab?
Here FE 2024. I just passed the FE Exam on my first attempt. I can be more proud. Thanks so much MARK for all the Free useful videos that you have put on this channel. These resources were instrumental in my preparation journey. I would like to give a few tips to future people planning to take the FE. Initially, I started my preparation on Mark's channel, but I found some of the problems to be quite challenging. Seeking additional guidance, I explored various channels until I stumbled upon @Genie Prep. Her channel features a comprehensive playlist covering all the subjects outlined in the FE specifications, except for the construction part. Working through problems alongside her, I found clarity and deeper understanding. Returning to Mark's channel after engaging with Genie Prep's content, everything made so much sense. Both channels emphasize effective utilization of the handbook, which proved to be immensely beneficial in grasping key concepts. In my opinion, the combination of Mark's and Genie Prep's channels is sufficient for passing the FE exam. However, for those seeking further familiarity with the exam format, I recommend practicing with NCEES practice exams, as I did.
I just wanted to tell you thank you. I took the test the past Nov 14th and I just got the result today and I successfully passed it. It was hard for me studying for this test. I’m from Colombia and no just the language but the content of the test kinda worried me a little bit but your videos were EXTREMELY helpful. I cannot say thank you enough, thank you for helping everyone that cannot afford an expensive FE course. Loved your videos and your explanation I wish all my professors back home were like you, school would’ve been way easier and way more enjoyable. Thank you again 🎉🎉🎉
For question 8, you could "complete/close" the rectangle and get an area of 12m*8m=96m^2 Then find the area of the bottom right parabola you get when "completing/enclosing" the shape into a rectangle by using the formula A=b*h/3 on page 39 of the most recent FE Reference book. This results in an area of 8m*6m/3=16m^2. After doing so you take 96m^2 - 16m^2 = 80m^2
Thank you mark. My FE result came today and I passed. Just letting you know that your videos have been great help for me in this journey. I'm entirely grateful to you for being such a fun teacher.
For question 5: It's more intuitive to me to multiple CosX by Cosx/Cosx to get CosX as the common denominator, then you have Cos2x + Sin2x =1, or 1/Cosx = Secx. Fewer steps and easy to head towards from the start.
I'm happy to share this news with you. I've been notified by NCEES this morning that I PASSED my FE exam!!! This is a milestone for me and the past week is definitely been one of the most torture weeks of my entire college career just waiting on the result back. Thankfully, it turns out great after all the preparation during the whole winter break. Thank you for your contents they are REALLY helpful. I didn’t study anything else but this and the FE official practice problem.
Hi Mark, I just recently passed the FE exam and wanted to express my gratitude for sharing your videos. It's really super helpful and took big part for me passing the exam. Thank you so much.
Here in August 2024. I really gave up trying to study for this exam until I found Mark's tutorial videos. As long as you follow along all his videos diligently, and study the practice exams, and practice practice practice using PrepFE, you will be golden! God bless you, Mark!
Thank you so much Mark. I passed the FE exam today on my first attempt. Your videos help a lot. I watched all your review session and bought an exam sample on NCEES site.
Thanks Mark, I came across your videos while looking for resources and they've been super helpful. Even though I don't have your calculator, it's helped recognize which functions the HP 35s may be capable of too!
Great video, thank you so much for all your help. I just wanted to say for problem 8, I started off the problem by getting 10 as well using similar triangles but the next step I did was use law of cosines to get my angle from the triangle formed in the circular segment(11,11,10). That's how I was then able to get my circular segment area and combined that with the area of the square and triangle. I hoped that helps
Maybe I'm not cut out for engineering lol. I tried to work out these problems ahead of you by pausing the video and using the handbook and idk if I got a single problem right.. I graduated 3 years ago so jumping back into this is very difficult
I use the same calculator and find it helpful watching which buttons you use. Maybe more light on the calculator and go slower so we can know which buttons to press. Thank you!
Hi Mark thank you for your TH-cam. I am watching your Mathematics . But FYI please , can you do minor correction for #13 and 14 question. Just add k after 4
Good question. This is the value of practicing with your own calculator as the two are different! The Casio uses A+Bx format for linear regression. See support.casio.com/pdf/004/fx-115ES_991ES_Eng.pdf The TI-36X Pro uses Ax+B. education.ti.com/download/en/ed-tech/858D1A4A484E493DBA150F4F3BD1DC9D/838E418957544F4784B8819BC5B2B67E/TI36PRO_Guidebook_EN.pdf
Thank you very much for this effort , i was wondering if i can find theory explanation before addressing examples , i've been working as design engineer for 14 years and i'm bit away from books for a certin period of time , what's your recmmendation to reveiw the theory ?
Unless you know every single number in a given population, you typically use sample standard deviation. Concrete break strengths are typically a small sample from a larger population or set.
For QS 18 shouldn't the Z value = -2 ; 4000(X)-4400(mew)/200(sigma).....If yes how would we locate the negative Z value from the given tables in the reference book.
The first time I took the FE, I was told that the TI-36X pro calculator was not allowed due to being able to type letters. I emailed a complaint to NCEES and about two weeks later I got a refund. One of the sections where I didn't meet the average was mathematics which was frustrating.
That's ridiculous because it states on their website and in the FE Exam Info by NCEES that the TI-36X Pro IS allowed, so you should've just been able to show them that, and they should've let you in. Anyway, glad to hear you at least got a refund for your unfortunate situation
@@sheed2819 I just saw this. I did figure it out. #1) Take triangle ABC. The only side missing is BC. Use pythagoreas theorem to find BC = 13. #2) Using similarity between the triangles, you can prove that ABM ~ CBA (They're similar triangles). #3) Because they're similar, you can set-up ratios between the relationship of their sides to solve for the missing lengths. The first length, for example, would be solved with the following ratio: BM/BA = AB/CB => Solve for missing side, BM = 25/13. #4) At this point, you could use two more sets of ratios to solve for AM and CM. For the sake of time, you might have realized that the only answer that contains 25 is B. #5) If you found all similar sides, the denominator for all three is 13 so you can just multiply it out of the ratio to get the answer is B, 60:25:144. If you want additional help, this video from Khan Academy contains a similar problem: th-cam.com/video/LrS5_l-gk94/w-d-xo.html
On #18 for the Zvar equation, why did the μ and X̄ switch places? Is it only so that the Zvar remains positive? Because I don't see a negative Unit Normal Distribution table in the FE handbook.
Don't questions 13 and 14 need to have a k in the formula for vector B in order for the math to work out to the chosen solutions? Otherwise the matrix for vector B should look like [2 , -3, 0], no?
I have questions about this page , I have B.S in civil engineering from Afghanistan foreign countries my English level is intermediate. Can I pass this exam? If anyone can guide my I appreciate because I really need guidance from you.
On Question 19, the formula on the handbook says y=a+bx and on the video the problem is done y=ax+b and we get 2 different answers. Is the formula on the handbook wrong?
From what I understand it's because Mark uses a TI-36X Pro and that calculator uses Ax+B. I use the casio and it's the same as the book, however I'm also still stuck on what to do if the equation is different. Have you found out what to do?

Good afternoon, If i use thoes three guides I should be okay. What are some more tips that you have as I take the test in two weeks
were there alot of fill in the blanks in certain topics?

Thanks for the kind words! Congrats!!! Dios le bendiga!
did you only study this course? or did you use other stuff to study?
did you find the level of actual test's difficulty similar to the examples provided here?
Good luck
For question 8, you could "complete/close" the rectangle and get an area of 12m*8m=96m^2
Then find the area of the bottom right parabola you get when "completing/enclosing" the shape into a rectangle by using the formula A=b*h/3 on page 39 of the most recent FE Reference book.
This results in an area of 8m*6m/3=16m^2.
After doing so you take 96m^2 - 16m^2 = 80m^2
Nice catch :)
Could have also taken the Parabola equation and added it to the area of the square.
2*8*6/3 = 32
6*8 = 48
32+48 = 80
Both are good!

for Q (8) FERH page 113 look for half parabola under area and centroid formula is 2(ab)/3
My biggest struggle with this test is time management so seeing the calculator tricks is amazing. Thank you
Thank you so much Mark. I passed the FE exam today on my first attempt. Your videos help a lot. I watched all your review session and bought an exam sample on NCEES site.
As per fe reference manual, the equation for linear regression is y=A+Bx , as opposed to y = AX+B
Thanks for this , I noticed that as well
Addition is commutative, and it is arbitrary what we call the constants.
He was using what’s In the calculator which is y=ax+b, check out 1:30:16

1:27:55 why is sample size 1? If the variable is not given and you need to solve the problem then you just assume 1?
For #19 my A value is -2.84 and my B value is 2.44. Not sure what I did wrong. Using the casio fx-115es plus

How to learn use this calculator? I didn't see that kind of technology in my country 😆

At 42:50 Question 8, you used area of trapezoid formula. Is this formula, along with other area formulas found in the reference manual? If so, where?
See page 111 in the Reference Handbook v10.1 for general shape formulas.
On #18 for the Zvar equation, why did the μ and X̄ switch places? Is it only so that the Zvar remains positive? Because I don't see a negative Unit Normal Distribution table in the FE handbook.
Essentially, yes. You'll also notice the diagrams for the z-var tables are opposite as well.
