FE Exam Transportation - Vertical Curve Problem 2

[@alejandroaleman3173]

You lit so many lightbulbs that were stopping points until now. I'm in debt. Really appreciate what you're doing on your channel. Keep up the good work!!!

[@laureencallos6447]

I'm taking my FE exam on thursday next week and your videos and materials are my main resources for reviewing. Please keep making these videos even for the PE exam. Your videos has been really helpful for me! Wish me luck! Godbless!

I'm confused conceptually - how is it possible that the elevation we found (268.3) is considered the lowest point, if PVI is technically lower than that?

[@anaesquivel3878]

Hello, Sorry Where did you get the first formula from? The STA PVC +Xm. Also when I do 265.45'-(-3.4%)(3/2) I get 265.501 instead. The same happened with your previous video:/ Thaaankksss

[@hjjjhh5774]

Thank you kenza for this video! So datum point will be reversed upward for sag curves. Is that I right?

[@kevinsifuentes132]

When do you use the tangent elevation formula?

[@monkeypolicd]

I need help with way advance problems, such as connecting two vertical curves with a constant grade.

[@DatNguyen-wi3fs]

the equation for "sta @ lowest point = sta pvc + x(m). Is this equation listed any where on the handbook or it's one of those we have to remember ?

[@themob24]

The figure for Vertical Curve on the Handbook shows that distance 'x' measured from the PVC. This applies for x(m) too.

[@armanyazdekhasti]

when we were finding the curve elevation you used Xm in the formula but its X not Xm.

[@hussainabdalla2372]

I wanted to know for Station at lowest point why did you add 4300 + 134 and not subtract? I understood from your previous video that to find you subtract Xpvc to the distance your trying to find.

[@hussainabdalla2372]

Also for Xmin why was that plugged in the curve equation instead of the distance between Xpvc and X min as done in the previous problem

thank for your help! hope you ll do videos preparing us for PE exam, have you taken the PE?

[@Genieprep]

Thank you for watching and I will post videos on the PE once I take the exam. Good luck with your studying!

[@shaysweeney5954]

Hello, and thank you for your excellent videos! Wouldn't the lowest point be at PVI in this case because the elevation at PVI is lower than the elevation at 44+34?

[@jlmeyer7]

The elevation at PVI is not on the curve. That is just the intersection of the forward tangent and back tangent projected through to their intersection. Just like in horizontal curves.

Hi thanks all videos are clearl

[@Mostafa-toofy]

hey enGENIEer , would you make videos about construction subject , which have information about project management , it have more complex issues in calculating prices and profit

[@Genieprep]

Hello Mostafa, I will be posting a problem in construction soon, but for construction, you need to know how to find critical path, how to find the float for an activity and some conceptual questions about project management. I hope this helps and good luck with your studying!

[@huseyin8017]

Thanks very much for the nice explanation , if we were given crest vertical curve question and asked to find highest point on the curve , will the solution be the same in the steps or different ?

[@Genieprep]

No problem and the steps would be very similar if we had a crest curve. I hope this helps and good luck!

[@huseyin8017]

Thanks alot very helpful

How can we solve grades from raw data?
