  1. If this were me, I would first try to estimate a discharge coefficient of the hole. Then I would numerically step through pressure drops and integrate the mass flow rate of freon leaving the system (depends on if liquid or gas wherever the hole is, though). From the known mass (or estimated) of freon in the system you can then figure out how long it took from the integral of flow rate across time. This is a total shot in the dark at it (not my forte) but I think that would get you in the ballpark.
  2. I still have a couple years to go on the experience train before I can get my license (yay for Alabama decoupling). I am at my last day with my current company in manufacturing and I am switching over to a large EPC firm, where I will have a lot more mentors and challenges to help me learn. I am really looking forward to the transition. So moving tomorrow, new job Monday, and then just enjoying my work and family. It will be nice to have my evenings back to being chill time.
  3. On the plus side of CBT, you can CTRL-F for everything in the reference. It made the FE quite easy. On the downside, its hard to have "spatial awareness" in a computer file, so looking around for a reference apart from searching can be harder, if you are unfamiliar with the layout.
  4. Dominant arm for 3 months. Ambidextrous for the win. Would you rather sit in an open office with an ice-crunching coworker next to you, or have a private office that you can't leave to use the bathroom during work hours.
  5. My alma mater still maintains a materials engineering department which is doing just fine (actually, just got a renovated building). It may not be as plentiful as Mechanical Engineering (which is 1/20th of the entire undergrad campus), but it still has plenty of students.
  6. Working a 6 day plant shutdown before changing jobs/moving at the end of the week. Busy busy.
  7. So there are a couple options you could consider. A rack and pinion would work, if you could find some small enough. Similarly, you could run a small belt between two pulleys, one of which is attached to your rotating link, and then your thumb device is attached to one side of the belt to slide it back and forth. As far as making the connection between the two links. You want a small shaft that will free spin relative to your gray link (that means your bearings need to be mounted in the gray link) and you want that shaft fixed relative to the black link (so you can find some method to attach the shaft to the black link, such as a key, a spline, weld, glue, whatever your application needs). On that shaft, you will also want whatever device you are using to rotate the black link (the pinion gear for a rack and pinion, or the pulley for belt drive system). The remainder of the drive components can be housed within the gray link, perhaps will a screw on end so that you can change it out over time.
  8. I know in AL, you have to include all experience, regardless of qualifying or not. I would double check this for you.
  9. Relatedly, is the thumb movement to control the rotation mechanically or electrically?
  10. First, labels are really helpful. Your description is terribly confusing. Let me make sure I understand you. You are trying to grip the gray link, move the golden nub linearly with your thumb, which when moved a full stroke, will cause the black link to rotate 180 degrees? What is the belt drive for that you think a bearing would accomplish?
  11. ABET can be important for jobs, but it is important for the PE. As has been discussed, there are ways to get your PE without having gone to an ABET program, but it is harder and carries more complications. I've come across several job descriptions that require ABET accredited programs; most of the time, you can glean that what they mean is "not an engineering technology degree." But you are limited if you do not go to an ABET program.
  12. I seem to recall that some boards have newly minted PE licenses expire ~6 months from initial issuing. Honestly can't remember why or which ones though, so take it for a grain of salt.
  13. Project scope determinations and proposal evaluations fall under "engineering" work. I would emphasize your work under this resident engineer and your relationship there. Also, emphasize the detail oriented nature of these projects and how you evaluated the project itself and the cost of each item. Perhaps you found ways to save money by selecting or recommending comparable parts from other vendors? The field inspections are a big thing - definitely bring out details there.
  14. Check the other threads. Thats not what this one is for.
