1. Ncees Pencil April 2018

You’re a stickler for details aren’t you? RED!
2. Ncees Pencil April 2018

Green means Go! Red means Stop. Pretty simple.

It could be worse. You could take tests 6.5 years apart and get the same color pencil. #engineerproblems
4. Best Way to overcome "time" anxiety

An alternate theory (not necessarily better, just different) is that the A,B,C,D counts are all equal, so as not to give statistical advantage to picking at random. For the PE this means each letter appears 10 times. If this is true... you may gain a statistical advantage by compiling a count of your confidently answered questions and seeing which letter is least represented. Obviously this would be your last resort, right at the end, for questions that you have no idea on. FFT

6. Bolt strength problem. Need help!

An alternative problem might include a bolt pattern that resists a compound load, so that the loads on each bolt are not identical. In that case, you would need to find a way to determine the worst case bolt loads and apply your safety factors there.

8. Things that are worse than failing the PE...

1. Buying a pizza in 2010 for 10,000 bitcoins.

14. When is it necessary to harden steel?

Thru-hardened steels are stronger, and the UTS is tabulated vs hardness value (link, see p. 2). Surface hardening (i.e. carburizing, nitriding, cyaniding, etc.) are often used for gears to increase contact stress resistance, while maintaining a softer core for resistance to shock, but hard enough to resist the bending stresses. In practice, for a thru-hardened steel (e.g. for a transmission jack shaft), a nominal stress is calculated, and a necessary safety factor is needed, so the strength of the material is defined, leading to the hardness specification on the drawing.
15. What is the difference between passing the PE exam on first attempt and passting it on 5th or 6th attempt? Do people ask later how many times did you take the exam?

A lawyer would not object to a relevant question, assuming your PE license is relevant to your expertise. By the way people, a PE license does not make you an expert: it states you satisfied the minimum requirement by law to practice in your field. Establishing your expertise in a court of law would require further interrogation. How many attempts at passing your licensing examinations would be relevant, as would your advanced degrees, positions held, publications, etc.
