Two of my coworkers tell me they looked into no other book but the CERM on exam day, both took WR/ENV and passed first attempt.

When you consider the moments about A, the horizontal force Fx 10' above ground is what you are solving to obtain. The axial force, the force along the alignment of the brace (at 45 deg.) is the Resultant of it's x and y components. Remember that R=(x^2+y^2)^.5. Anyway, just need to translate...

No hay de qué, a tu servicio. At least on exam day if we're given Q and TDH we'll know exactly what to do.

Table 18.8 on pg 18-10 of the 11th CERM shows common synchronous speeds (n values), in the U.S. The frequency is typically 60Hz. So from this table highest assumption would be 3600 instead of 1800.  For Q=10cfs (4488.3 gpm) and TDH = 1200', specific speed is 591 for n=1800 or 1183 for n=3600...

This type of problem sounds really familiar, is 'specific speed' mentioned at all in the solution? I have a copy of the 10th CERM here at the office and on page 18-13, Example 18.5 solves for specific speed using equation 18.28 and uses table 18.9; for a specific speed of 595 - radial vane is...

i just had a footlong, wheat, chicken oven 'crisp', the thing tasted terrible, but the girl that made the sandwich was cute.

And don't forget, if you want to be a licensed professional engineer, which all Civil Engineer's should be, you have to take 2 huge exams. They're both 8 hours long and have the tendency to make people feel like they've been beaten to a bloody pulp afterwards. Many people have to retake the...

Where I work, the Civil Engineering Dept. has several PEs and EITs, the Environmental Dept. is much smaller and it can perform all it's work without a PE.

The NCEES 2011 sample question #512 is a gimme question because it's 90 degrees, in the CERM it straight up says Q=2.5*H^2.5. If theta is some other value, then without correcting it, the All-in-one is going to cost us this point. The equation should include tan(theta/2), not tan(2*theta). I...

Right on, appreciate the help.

Thanks for clearing that up; I nearly blew a gasket when i got to the end of your first post. In this sentence: 'it takes about 10 times the wall movement to develop full passive resistance as it takes to develop the full active forces.' how is the 'development' of those forces manifested, soil...

I've reread the CERM and All-in-one chapters on retaining walls and am still having issues.  I'm having trouble with the statement: 'The lateral strain required to fully mobilize the soil passive pressure is much greater than that required to fully mobilize the soil active pressure.' According...

We made all these technological advances so that we didnt have to work, now we're complaining that theres no work to do.

Another plus about the all in one is it fits perfectly on the console of the exercise bikes at my gym. Working out and studying become one.

When I took it I only studied the Limburg and squeaked by.

Thanks for that response. I've been trying to get a grip on what to expect on test day and I think that'll be my last question on that issue.  And, That's a cool pic of you and your boy.  To summarize what I've learned so far:    Each person's PE exam experience is unique. Success or failure...

Fable II was a good time for sure; regretfully, I never did check out III,

Something I've been wanting to ask about the April 2011 exam... were the 2011 NCEES sample questions for each depth topic available prior to the exam? If so, I'd like to see opnions on the difficulty level of the exam compared to those sample questions. People have posted that they studied...

It's a rectangular channel with a 'step in the middle' right side is 50' wide and 10' deep, left side is unknown' wide and 6' deep. n=.14 left side and n=.05 right side, s=.001 ft per ft. Need 3000 cfs, find unknown width.

My boss has expressed the same confidence in me. But, the fact that there is a chance I won't pass goes without saying. It'll be crappy but it won't be the end of the world if we get to take it again. Reading all the posts from past test takers, it's like a broken record, the morning is...
