IN the 13th edition of practice problems for civil engineering PE exam, on page 17-15, why is there a 1/2 in the formula, where it says: "to calculate a loss for any other flow in the upper branch" Ef upper 2 = Ef upper (.....) in that paranthesis i didnt understand why there is a 1/2 in the...

thanks a lot , i understand about the determinate and indeterminate portion now... i only asked about the design because they specifically write it in the ncees exam specifications for str am. they are listing beams, slabs footings under member design they also wrote dead loads live loads...

for the structural AM portion Can someone answer 1) if there are any indeterminate analysis 2) Also I can not find any beam or slab or footing design problem anywhere, which is listed in the topics for the AM portion. can someone guide me to somewhere which may have those type of questions...

in six minute solutions for geotechnical for civil pe exam, question 72, why did we use no soil information given in the question, to calculate the capacity of the pile? For the people who doesnt have the book, it is a question that asks pile capacity, which gives the hammer drop distance per...

In question number 69 of six minute for geotechnical, for PE exam study, it tells us to calculate the skin friction based on Beta Method, and uses cohesion of the soil. no angle of friction between pile and soil is given, the question doesnt talk about it. so it uses tha beta method and...

in question 17-2 of practice problems for the civil engineering pe exam by michael lindendburg, 13th edition, there is a pipe that connects points A and B. it gives pipe length, diameter, pipe material, temperature of water and the flow rate Q. B is 60 feet above Point A. it asks the pressure at...

okay thanks now i understand the geometry. based on that understanding, i looked at the solution again. this time i saw that subtracted the active pressure from passive pressure at the portion below the dredge line. so they made Kp x gama soil x height below dredge line (minus) Ka x gama soil...

Hello, For the question #86 on the latest version of Six Minute solutions of Geotech, there is an anchored bulkhead supporting an excavation wall. I can not construct the geometry of the problem in my head.. so i couldnt understand the solution. For the ones who dont have the book, the...

When calculating the active or passive earth pressure at retaining walls, if there is friction between wall and soil, and that friction angle is given , then we use coulomb formula (that long one) even if there is no incination of backfill or wall correct? if so, in question 76 of six minute...

In six minute solution for geaotechnical, problem 51 you place a very large area of fill on a clay layer of 30' thick. water table is at first at ground surface at first. they ask the consolidation settlement of clay due to the loading by the fill surcharge and also they are saying that the...

Hello, In the NCEES Geotechnical afternoon sample questions, question 520, for the depth while calculating the D, why do they take 2 feet and not 10, which is (2+8) feet up to the overall ground surface? for the ones that do not have, the question asks bearing capacity of a footing in the...

Hello On 6 minute solutions for geo, problem 42. why does it say it is normally consolidated and take only primary consolidation into account and not secondary consolidation as well? it is basically a question that has sand and below the sand clay. you excavate some of the sand and refill and...

i also definitely suggest a construction specific study book, as well as the references mentioned in the site i mentioned above. i was first considering construction until a couple weeks ago and bought them and although i dont need anymore, they are really informative it seems

i suggest 6 min. i am studying it for geo right now and it is really good i also got many free and good information on learncivilengineering.com website. dont forget to check it out

Hello, On question 33 of six minute solutions for geotechnical, why do they take the total stress and not effective stress for shear strength calculation, can anyone tell me? for those who dont have that book, It is a question that basically gives the thickness of a cohesive soil with also...

thanks. and i forgot to add an important item in my question... do they give redundant data that we wont need to use in some questions?

I would like to hear experiences of people who took the geotech depth. when i asked ncees if i need any real world design experience in order to make assumptions from real world during the PM, and without those assumptions questions are solvable or not, all they gave me is a copy paste message...

shape factors were slightly different in the "All in One" book by goswami. I agree with Terzaghi. because there is differences they should give those - i hope... i didnt look at DAS books yet or geotech engineer's handbook. I suggest look at those too and compare the factors. if you selected...

if you read the references in this tread for geo and follow the link for the other post you will have your references for geotech

Hello, Can someone write the chapters not to be studied for structural AM sections from CERM please? Structural goes from 41 to 69 in CERM. But some of them are definitely not included in AM. the reason I am a little confused about which chapters to skip is I guess the following questions...
