    Material Properties for Vibratory Load

    Pud- Dupont Delrin 100ST. Word through the grapevine is they are unable to source/produce one of the critical additives/modifiers, and several other resin manufacturers/compounders are similarly unable to provide their catalog equivalent material.

    Material Properties for Vibratory Load

    I am researching alternate injection molding resins due to material supply availability (i.e. we're about to run out of our qualified material and can't get more). Use case is for threaded fittings. Specifically, I'm wondering what material properties are most important when considering the...

    Annual Goals

    Hello all- I've recently started a new job (my 2nd since getting my BSME). I moved from a company that wasn't big enough to be considered even a "small" company into a multi-national behemoth with all of its associated procedures, planning, and documentation. I appreciate the structure...

    How to resolve issue with boss?

    As a young engineer, I would reply with this advice- Yes, you made a mistake by saying "no" to your old boss. At this point, that is done and in the past, so just move forward. If your new boss is your direct supervisor, that is who you should be contacting for work if you need something...

    LEL and H2S settings for crude oil

    So it sounds like the required ventilation is 6 or more room changes per hour, with higher ventialtion capacities required if 6 RC/h is insufficient to maintain vapor levels below 25% LEL. Kind of like a car warranty: 5yrs or 50k miles, whichever comes first. Only here it's "whichever is greater".

    ASME U stamp requirement for quick end closures of launcher and receiver

    I am not an expert when it comes to ASME B&PVC, but my understanding is: (1) Just because something doesn't technically fall under the "pressure vessel" definition as indicated in Section VIII, Div. 1, doesn't mean it can't be fabricated to those standards and U-stamped. I would have to sit...

    Social skills, interpersonal skills etc. for engineers

    I think there's a distinct difference between idle small-talk and actual interpersonal skills. While I'm not going to be rude to colleagues, I also have work to do and don't really need to know about your flat tire or your son's soccer game. Small-talk has its moments, but they are relatively...

    220/1/50 @ 60Hz- Effect and Consequences

    waross- Thank you very much. I greatly appreciate your taking the time to dumb it down for me. I'll look into getting an autotransformer to step up the voltage ~20% and swapping out the capacitor for one with ~70% rated capacity. itsmoked- Yes, I am [smile]. I'll admit that I probably would...

    220/1/50 @ 60Hz- Effect and Consequences

    I'll pile this on here, if you gentlemen don't mind... I'm afraid my tiny company has no electrical engineers around for me to pester, so I'm left to bother you all in the hope you'll grace me with some much needed knowledge. Trying to calculate PF 115V/1Ph/60Hz motor, 1.10A, 3250 RPM, 1/8...

    220/1/50 @ 60Hz- Effect and Consequences

    So reading the FAQ, my take away is: --50Hz motor to 60Hz supply, constant voltage- generally you're ok as far as the motor goes as long as the increased load HP requirement due to higher RPM doesn't cause the full load current to rise above the current shown on dataplate. Biggest issue here...

    220/1/50 @ 60Hz- Effect and Consequences

    Thank you. I'll admit that I have not used the FAQs before and did not realize that the website search does not automatically include them when searching for a topic. I'll be sure to check there first in the future.

    220/1/50 @ 60Hz- Effect and Consequences

    Hello EEs- For reasons that are somewhere between "trivial" and "pipe-dream", I am trying to learn about the viability of utilizing a centrifugal pump with a nameplate rating different than the electrical supply. I've poked around this forum and gleaned some understanding, but I'm afraid the...

    O-Let Welding

    Thank you for your replies. Not sure why I didn't think about a 1x1x3/4" reducing tee earlier. Probably would have gone that route if I'd thought of it sooner. Unfortunately, I believe the spool in question is needed to be finished tomorrow to be assembled and sent to painting. I think, in...

    O-Let Welding

    I know this topic has been beaten to death, as I've gone through pages of search results on the topic. I wanted to throw an application/proposed solution out to see if there might be something else I should consider. 1" Sch.40 SA106B pipe requires a 1/2" NPT connection on the side. GTAW...

    Recent graduate and unemployed

    Did your co-op position not "excite" you, or were there other factors that prevented you from being employed there after graduation? I ask because most of the guys I know who did co-ops turned around and had full-time positions with those companies months ahead of graduation. University career...
