no it is not two dimensional the handle part is on the other plane as I wrote so it creates torsion in the shaft. i can not draw here unfortunately

I was solving an AM problem on PPI exam cafe online . (Question number 59) Think of a simple mechanism similar to a door knob, fixed to a wall only and free hanging like cantilever, with the part where you hold with your hand in the perpendicular plane. Imagine you are pressing with your finger...

Thanks so much this really helps

Hello on All in One latest edition page 384, the design of strap footings is asked. In addition to axial loads, the also calculated a moment based on the axial load of one footing times distance to the other footing and borught it as a moment to second footing. and based on that moment, from...

here is a very good source i found on this triaxial test : http://www.geocities.ws/dominic_trani/paper4.html i read CERM and All in one, but here, it is explained much better. Hard to believe when the two most popular books on the market can not explain this good enough....

when doing the consolidated undrained test, first we apply the chamber pressure and let the pore pressure develop in the specimen to dissipate, so it drains. and THEN we close the drainage line at the top and bottom and apply axial load, so the name "consolidated undrained". I understand this...

in a question i am solving about triaxial test, it says: "In a drained triaxial test, a specimen is confined under pressure and axially loaded until failure." but drained means, we let the specimen to drain, which means it must be unconfined isnt it? why do they say confined? what am i missing...

for a square footing, i know the shape factors are not always the same but i saw one which is very different when i was solving a question for PE preparation. for example, in the formula I have, there are shape factors of 1.3 for c, 1 for q and 0.4 for gamma. but on a question i saw, i saw that...

brittle because you are below PL, so in solid state.... right?

In a question I am solving it says the following for PE exam Geotech it asks: A 4 x 4 ft footing is in sand for which the bearing capacity factor is 15. The sand is intended to limit the applied pressure on this footing to a value that will control settlement. What is the modulus? First of all...

The correction factor for N value, SQRT( (2000/efective stress) ) does the 2000 have unit? I thought it had unit of stress so this factor is without unit but in PPI exam cafe online questions, Geotech AM question number 21, they took this 2000 without a unit... are they wrong?

Right !! When preparing, I am having lots of fun right now for sure :P

i understand how we obtained overhaul distance. but then, how can you make that logic proportioning? i dont understand the logic here. with the same logic, in the attachment it said freehaul volume = overhaul volume.. why?

ok so by saying "bound" 3 ring binders are also ok? i thought i needed to go to staples to bind everything - not my notebook but the other stuff that i print from useful pdf reference materials... 3 ring binders are ok for sure? xeroxing my notes sounds like a very good idea.. just in case...

Hello, I know that any material you bring to the exam must be bound and as long as it is bound they allow it. Does this include my handwritten notes too? I wrote down ALL the formulas I encountered during my preparation and wrote explanations near them, and now it accumulates for more than 30...

yes the book gives it as 2-2.5 fps. so this was just a knowledge question then.. no calculation or anything?

in the attachment i downloaded from learncivilengineering.com site for the earthwork mass diagrams, in problem #4, it says overaul volume equals freehaul volume. why is that?

in the practice problems for civil engineering pe exam book, question 19-5-d, on the solutions page, 19-9, it calculates q/qfull and then i didnt understand how it calculates d/d full, can someone help, who has the same book? or in general how is it done, it refers to the chart on CERM Appendix...

on a pipe network analysis problem, when comparing the heads between the two adjacent points, when writing the energy equation, they took into account only the elevation and pressure heads. why didnt they take velocity head into account? This is the question In the 13th edition of practice...
