Got asked by a student today if I would consider myself a skilled CAD user. Not really related to the subject at hand and they've never seen any of my CAD work... My answer was that yes, I would consider myself a skilled CAD user. But it got me thinking. What makes one a "skilled" or "expert"...

thanks for the help guys, much appreciated :-)

If we assume that 1 SEK = $10 (not quite correct but somehow this seems to hold true whenever I'm comparing prices between here and the states) then an engineer would cost roughly $6000 per month (about $3000 salary before tax and about the same in various social fees and whatever, very rough...

So, I scanned this section for a thread that sort of answers my question but once I got down to 2009 I figured I'd better ask... A small company is looking to start up locally and need to look into what CAD software to use. I may be one of those who will be active in this company, or I may not...

there does seem to be a lack of high-school teachers in engineering and it does look like it's going to get worse. I guess most engineers don't find teaching to be sexy enough and most would-be engineers consider the education for teachers to be full of nonsense. then again, these jobs are...

this has sort of been covered in the "to switch or not to switch" thread, at least partially. I'm currently working as a designer for a large company and have gotten pretty good at designing plastic components. I've been there for a while and it used to be a stable place except now HQ has...

Ok, so the idea of shaping the channel to a cone around the fan outlet worked. Gave me a 10% increase in airflow out of the channel outlets and 5% decrease in energy consumption. I'm now concentrating on the frond end of the system, the inlet. The original inlet had several small ribs and we...

The system is acceptable, but still needs improvement as the requirements keep going up for energy consumption and cost reduction. But yes, more radical solutions should be tested as well in case the opportunity of a re-design presents itself. Because sooner or later (when the customers start...

the slits are rectangular cutouts in the face of the duct with the short side of the rectangle perpendicular to the flow. There is no geometry to help guide the air towards the outlets. According to an analysis we ordered from a company late last year, the highest pressure is just behind the...

berkshire: it's all about cost. That and our lack of knowledge in aerodynamics and fan blade design (someone tried designing a radial fan blade for use with this motor some time back and the results were pretty poor). Mike: you're probably right. and I'm sure my upcoming measurements will show...

maybe I need to explain a bit better (and if this doesn't do it, I should probably provide you guys with some sketches to show you what I mean. I'm not very good at explaining stuff anyway). Are you guys familiar with frost-free freezers? that's what this is. The system is divided into two major...

I'm trying to measure the change in efficiency for a duct system. As it is, the fan is blowing air straight into a wall and the air then travels down a channel towards a series of outlets (imagine a fan situated in a short circular tube connected perpendicularly to a flat and wide rectangular...

Haha, thanks. I thought "analysist" looked and sounded a bit odd after I had posted, just couldn't get my brain to connect :) Happens to me a lot it seems :D

Apparently, with the last re-organization of our R&D department I was considered to be sort of our "expert" on FE analysis and mechanical strength calculations. Yes, given the limited education I have regarding FEA, this is worrying. The software we use for FE is Catia V5 and we currently have...

in this case, I have 2 cylindrical steel rods completely encapsulated in a plastic structure, simply supported at both ends and carrying a load of 200N. the rigid connection results in virtually no deformation at all for neither the plastic nor the steel rod. the smooth connection seems to...

I'm doing a series of FE analysis on a plastic shelf with steel reinforcement bars and just today noticed an annoying error I made: I have been using a "rigid connection" between the reinforcement bars and the plastic. As I understand it, the rigid connection results in an infinitely thin...

I found a measurement for a similar lamp, though the housing used was better ventilated and provided more space. it seems I should consider temperatures of at least 130°C (the maximum temperature reached during the test with that other housing).

I need as much light as possible going in the radial direction of the bulb, towards the floor (the lamp is mounted so that its axis is parallell to the floor). The lamp which is supposed to be replaced is a 25W halogen spotlight ("decospot" something or other) and though I'm convinced we're not...

I've been given the task of trying to fit an existing lamp into an existing component. I have been told to just make it fit, meaning that I may modify component carriers which were previously sacred. Now that it seems I have found a solution for the bulb (and socket) to fit there is the problem...

I'm looking at how to improve a component which is in direct contact with a heater. The objective is to improve heat transfer between the heater and this component. I have a pretty good idea of what I want to do for my analysis, but I'm not sure it's doable within GPS. I want to apply a...
