It's been 4-1/2 months since I was laid off. I've been job hunting and doing the support activities but it's turned into a waiting game with only a few hours per week now required. I'm bouncing off the walls lately and it's hard not to have much meaningful work to do on a daily basis. So, to...

Greetings, all. As some might know, I'm in the job market again. Although I've got nearly 15 years under my belt, I've never been in one industry long enough to be an expert at anything. This leads to my present quandry. I've applied for an ME position at a local company that also has a...

Greetings, all. On the day after Labor Day, I had the misfortune to be laid off. I'm now undergoing the painful process of trying to find a new job. I'm in the unenviable position of being 42 years old with my longest tenure at any job being 4 years and having just been laid off for the 3rd...

Does anybody know what happens to a SWX license with the dissolution/bankruptcy/liquidation of the corporate owner? I think it's non-transferrable which implies that it dies with the owner but that seems sort of unfair -- after all, it's an asset that was paid for with a license and a...

I'm not sure where to post this so I'll put it here since it's sort of "How Do I Get Ahead" issue. The start-up for which I work is looking ever closer to flaming out. Has anybody ever been through this? Do you have any advice? Are there any steps that I should take in order to protect myself...

I'm trying to delete some screens in ProTool and it won't let me because it says that they're being referred to by other objects. I've deleted all the referring controls but I still get the message. Running Cross-Reference yields the following screen: Can anybody explain this to me and tell...

I have a processing plant in China with a range of motors, most in the 3 to 20 hp range but one that's 200 hp. Most are driving centrifugal fans. They run about 18 hours per day. Recently we've seen our supply voltage drop to as low as 340 volts (as opposed to the 380 VAC motor ratings). My...

I've just been told that motors run through a VFD shouldn't be run under 20 Hz... No reason provided, just the advice. I can't think of any good reason except that the cooling drops with the speed. In my case, I'm typically drawing less than 50% of FLA (though in a continuous-duty application...

I have an application that was defined by people no longer with the company. Without going into too much detail, I've got two motors of different sizes that are driving rollers in opposite directions. The rollers are used to shear material passing between them. The slower (and smaller) motor is...

I'm just looking to bound a problem: Presuming a 3Ø motor with a full-load draw of 300 amps, what's the approx current draw per conductor feeding the motor? In the deep recesses of my memory (I took electrical machinery about 20 years ago) I seem to recall that it would be sqrt(2)/2 * FLA. Am...

To all you road warriors: Beware of changing your system date or language. According to Siemens Tech Support, that's why I've had my keys take a dive twice in 5 days. They say you should dump the key to a flash drive before futzing with the system settings. -------------------- Bring back the...

Hi there. I'm still coming up to speed with Step 7. Looking at the assignment chart shown, I see an overlap on one address. (Sorry, I don't know how to make it bigger...) Does this mean that I've really got conflicted memory? I've checked my assignments and none of my symbols overlap so if...

In an effort to convince a supplier to share his SWX files with me for use in my own system layouts, he's expressed concern about his assemblies. I've suggested using the "Save As Part" approach. He said that they've found that the dimensions are not always faithfully maintained in the...

I've read many of the posts about respect, image, etc of the enginering profession. I've just heard a couple of ads that touch on this. There's a LASIK surgeon in the SF Bay Area who advertises on the radio. They start in his qualifications, "Harvard MD and degreed electrical engineer" Wow, a...

I'm an OEM who's shipping a heavy piece of equipment to China for installation in a warehouse. The original spec that my company provided (before I joined) called for floor loading of 9800 kg/m^2. Now, at the 11th hour, they're saying that the maximum floor loading is only 500 kg/m^2. I just...

For those of you using SolidWorks in machinery design, how do you deal with your schematics? I currently do them all in AutoCAD (for which I have some plug-ins that facilitate its use in schematics) but I'd be interested in transitioning to SWX completely. Does anybody use SWX for schematics...

I've got about 1500 hours of SWX under my belt but have had no training. I've brought it into two tiny companies as the only user and haven't had the benefit of either seeing an efficient deployment nor working as part of a team to develop one. I've been struggling with finding the best way to...

In the US, the 'standard' drum size is the venerable 55-gallon drum. Does that standard vary country-by-country? What standards are used elsewhere? I'm specifically interested in China, India, & the EU (Dutch & Brit votes notwithstanding...) -------------------- Bring back the HP-15...

As part of my BSME, I took a welding survey course but it we just learned the very basics of stick/TIG/MIG along with a dose of oxyacetylene tossed in. I've several times been through the welding sections in Shigley's machine-design text and his machine-design handbook. I've also read sections...

For some reason when ACAD 2002 installs off my IV Series 6 CD it doesn't include the icons for the 3D Modify commands. I found them on the web awhile back but lost them and can't find them again. Does anybody know where I can find them? -------------------- Bring back the HP-15 www.hp15c.org...
