Thank you so much Sac...I really appreacial the help..This site rocks.

The first part is the simpliest. Just need to find SSD at the given speed limit, then satisfy one of the two basic equation for sag vertical curve. The meat of the problem (at least for me) is finding out how the offset distance was calculated, especially the value 106.05 in the calculation for...

I though I understand vertical cuves fairly well, but ran into this problem that's I am not getting answers for. Can someone please explain how the offset distance was calculated for part "C' solution. Isn't the offset distance supposed to be the difference between the low point elevation on the...

I am intersted in finding the equation also!!

In Highway Capacity Manual example problem #4, gives an example of a freeway segment with grade in segment one of 3% and length of 3000 ft. Segment two of the said freeway has grade of 5% and length of 2600 ft. They gives other parameters then asked to find the LOS for the upgrade and downgrade...

Is it safe to assume that well drawdown problems will not be on the AM exam. NCEES does not list this topic exclusively on the exam outline. What are other test people doing with this topic. I plan to take Transportation depth.

If in my calculations I come up with the following answers" Ultimate Bearing Capacity= 9877 psf Net Bearing Capacity = 9523psf Maximum applied pressure = 5079psf (psf= pounds per squafe feet) If the problem ask "Is the footing sized correctly". I know my answer should be no, but I don't...

How long after receiving you failing grade did you actually pick urself back off the floor and started studying again for the next test. I failed the 4-10 exam and find it less appealing to pick up the books again. How did you motivate yourself to start studying again. A few more questions...I...
