Where did you find MMC and LMC in the handbook? I didn't hear you mention the page number 8:55 and don't see your explanation in the handbook

Best FE youtuber

holy smokes.. after 4 years of high school and 5.5 years of university.. i finally have a concrete answer and method to differentiate the two. Ive always struggled to understand when the switch occurred and the "why" behind it all. Thank you so much.

Thank you

Im averafing around 68-70 percent .

Thanks helped a lot

Where in the handbook is the L.atm conversion to Joules? I don't see it on pg 3, only for the universal gas constants

would we get a question this long on the FE exam knowing that there's so many questions and so little time???

If the aquifer doesn't have an uniform thickness, how do you calculate the area? Do you use an average thickness from different measurements along the aquifer?

love these explanations!🙏

why is my approach wrong? on this diagram, 1 lies on the sat liquid region, we know that the pressure at 4 and 1 are same, so I find the hf at that place, given the h must stay constant, hf=h4, which is what the question is asking. but my answer of 419 kJ/kG isn't correct

I’m cooked

how do i solve last question at end of video?

what if the beam is frame

Question: FE handbook: Latest Edition Pg#263... Effective Horizontal force Formula PA2 = σ1' KAH2 +1/2 (σ2' - σ1') KAH2 In 1st part of formula given(σ1' KAH2) which KA value we use if unit weight are different for dry and saturated conditions (dry and saturated).

why is this ideal plug flow? assumed CMFR (in current handbook) with "continuous plug flow reactor" in the problem statement

g? Did I miss something?

The second half is completely wrong. just ignore

I wonder why you did not consider reaction forces at point A

Bro act like as if he is talking in sign language

Is 19.97 kW correct for the Power question?

Please excuse my arithmetic mistake. The correct written solution is shown below: www.directhub.net/wp-content/uploads/2024/09/image-2.png

The animation is very good

The FE really isn’t that difficult. Shouldn’t take more than 6-10 weeks of study time

For Impulse Momentum priniciple,it is the change in force or the net force in the system is equal to change in momentum right. why did you use F as the resultant force. The resultant force should be zero right since it is acting equal and opposite direction.

Correction: For any softening problem we will use the EQUIVALENT RATIOS. Using this ensures the amount of lime (or soda ash) added will exactly match the amount required to neutralize or precipitate the hardness ions, based on their charge equivalency. The Stoichiometric Ratio isn't accurate enough since it's based only on the balanced chemical equation which tells us the ratio of moles of reactants required to completely react with each other. A better method is to use the equivalent ratio which accounts for both the charge and the amount of substance. It is used because water softening processes typically involve ionic reactions where the focus is on balancing the positive and negative charges rather than just the moles of reactants. The corrected proportion equation should be: 2 equivalent of Lime/1 mol Mg(HCO3)2 = X / 50 mg/L The equivalent ratio for the reaction is equal to the molar ratio. This won't always be the case but it is so for these chemical softening equations.

Thanks Instructor!

I believe the answer to the last question is 3.09 kg/s (B)

Where can I find pre math crash course?

Study extra hard.

Why is the value of K not taken to 1 in Manning's equation, whereas it is taken as 0.849 (SI units) in the Hazen-Williams equation? Shouldn't K in Manning's equation also be expressed in SI units?

this is the best video on engineering econ for the FE Exam

Thanks dude. I take the test tomorrow

I just want to know that I really appreciate these videos. You do a good job, and it has really helped me, thank you.

Your question on it being a face or spade card, your question did not differentiate it being a face spade card, so why is it not a face card of the other suits?

Using the FE HANDBOOK frame equation for the first problem we get: m = 4, j = 5, r = , and c = 1 3m+r ? 3j+c 18 > 16 --> Indeterminate to 2°

What other stresses are present, and where are they, since the simulation you set up isn’t pure bending?

Are the definitions located in the FE Handbook?

i think for the sake of saving time, its easier to just estimate by using the 45 degC numbers instead of interpolating

area is divided out on both sides of that equation so it wont matter either way

Sir I just want to let you know that I passed the FE by watching your videos + practice. You rock! Thanks for all the great vids!

Height is wrong

My strategy has always been to link topics as much as possible. Say I learned about semiconductor physics today and BJT-MOSFET circuitry tomorrow. I must remind myself what is happening at the bandgap/electron level while this circuit is functioning. Then the next day I do Karnaugh maps and remind myself how the logic gates in a flip flop function at the MOSFET level. The next day I write in C++ and I remind myself how Assembly coding functions by managing flip flops which are just semiconductors and bandgaps. Everything is connected to everything. Don't suffer from tunnel vision.

I'm about to take my FE exam and you are making thermodynamics easy to understand! Thank you so much.

WATCH OUT! @25:17 the FBD of box A should include the friction force between block A and block B. The corrected FBD is shown below: www.directhub.net/wp-content/uploads/2024/08/image-26.png

Hi Farouq, @25:49 shouldn't there be a friction acting between A&B acting on Block A? I just wanted to be sure. Thank you for the videos! I am feeling confident in the exam on 08/26!

Understand well thank you ❤

hello! I have a question, are your FE review videos also work for the mechanical FE exam as well?

Hi Faruq, I hope this message finds you well. I am an international student currently preparing for the FE exam. I have been using the "FE Review Manual" by Michael R. Lindeburg (Third Edition) for my studies, but I’ve found that it doesn’t cover all the topics or provide enough practice problems. As an international student, I find the cost of enrolling in your course to be too high for my budget. Could you please recommend a comprehensive study book that covers all the necessary topics, along with a good practice problem book to help build my confidence? Thank you.
