Hey Mark! Thank you so much for your videos. I passed the Exam. It was really helpful to me. I did my exam after 10 year from graduation. I happy to say inly 2 months work hard with your videos.
@aditiadarajat3774
Hey Mark! Thanks for your video. It is really helpful during the exam. I received the notification that I passed the FE exam this morning.
@selaseasamany7274
Thank you so much, Mark. I passed.

On prob 7, he should've written (100)^3/1000 when doing the conversion from cm^3/m^3 to kg/m^3 I believe. 10^3/1000 = 1. Thank you for the videos Mark! Exam in 2 days!
@sanjaynanda5800
Hi Mark, thank you for your dedication to helping students. It is much appreciated. I passed my FE thanks to your resourceful videos and review packets. Onward and upward!
@aman_lu
Thank you for everything Matt! Flow nets came for my test. Just know how to read the points on a flow-net graph.
@mr.bond0774
Hey Mark, your videos are really awecome! I'm sure I can pass the exam after learning all of your videos!
@swetatripathi-cdot4642
I really appreciate these videos as well as your stories!!
@mustafaadeeb5140
I passed , thank you so much Guys my advice to you , listen and understand every single word he’s saying

For #11 at 1:13:29, I'm wondering why you don't consider the saturated unit weight of the soil that's submerged in water? I haven't taken a soils/geotechnical class yet so I'm not sure if my concept is correct. I used formula in reference manual to get (gamma)sat and used that as (gamma)2 in the Vertical Stress Profile. Thanks!
@matthewspector8122
Can you explain why you choose to do a 1 ft section for problem 14 rather than just doing it with the 5x5 footing?
@kenlua6064
Hi Mark! Thank you for your videos. Will take the exam in a month and it helped me a lot to refresh with all the concepts. For Question 13, I read somewhere that "Normal stress at failure" should be at the point where the mohr-coulomb failure meet the Mohr's circle and not the major principal stress which you used? Please can you clarify?
@brunogm6096
Great Video Mark! One question: On problem 18, the equation used for TFF doesnt seem dimensionally correct, C*Ls (kip/ft) + Wn*cos*tan (kip). The equation is pulled from the handbook, so I am not sure whether it is calibrated to work that way or if Wn should be divided over the length in the second part of the equation.
@sheilacatungal1194
Good day Mark. I have a question in no. 18. Did you make Ls an area? Based on the video, you converted the length to ft^2. I hope you will notice my question. Thank you 😊
@ramtinazami2850
Hi Mark, Thank you for the great videos. One question regarding question 14. The dimensions of the footing are given as 5x5ft but the thickness is unknown. The second approach for solving the question involves calculating I (Moment of Inertia), and I see that you are not using the thickness of the foundation to get the moment of inertia. However; I think the way the footing is bending, the Moment of Inertia should be calculated as width x thickness^3 / 12. and not width x length^3/12
@DirtyMobbTV
Hey Mark for (E) the equation is uses specific weight (gamma) so I think we have to multiply by gravity (32.2 ft/s^2) since you gave a density of 115lbs/ft^2. Look at the units. Even if you square the 8ft….. the answer would be lbs/ft. Sorry I am studying back over your notes because I my test is scheduled for May 2nd!!!! Please let me know if I’m looking at this wrong
@degnaw
Thanks for posting this! Question on #18 - How do the units work for the Tff calculation? When doing c * Ls, you converted the units to lb/ft, but it's not clear why it needs to be lb/ft instead of (say) lb/inch. Is the 30-ton weight of soil given implied to be for a 1-foot cross section?
@alfredoramirezmorales5912
Thanks for the videos! In Q12, the density (rho) shouldn't be multiplied by gravity acceleration to get the specific weight (gamma)?
