OK Thanks. That's probably all I need to know. I can usually figure out the easy ones, but couldn't quite comprehend this diagram.

Can someone help me understand what this solenoid is doing? It's somehow integrated into a switched shutoff system. I'm trying to figure out if I can jump two wires or ultimately add an on-off switch in line somewhere between the switch and this solenoid. Thanks for any help. click to...

OK, thanks for the response.

I remember calculating volume by revolving shapes around axis using integration in school. I have an arbitrary shape shape that has no easily attainable equation, if I know the area of that shape, can I calculate the volume? This is an example. I know this area, and want the volume if...

I'm looking for household liquids, preferable kitchen/cooking liquids with a low surface tension. I know of soap water, alcohol, and found olive oil. Any other ideas would be appreciated. I'm looking for something in the mid to low 20's mN/m or less. Thanks, -Eric

For my ME degree, we are only required one 5 credit "chemistry for engineers" class. It was PITA too, probably because they throw so much at you at once. We can also take two normal chemistry classes as well, but most battle through the single class and be done with it. Chemistry is so broad...

A well respected cohort whom I work with once said while driving along the highway: "Look out the window and everything you see is created by either an engineer or God" Made me laugh and it's a pretty bold statement, but really most of the things you see today, at some point an engineer is...

Thanks a lot guys. I found some clamp meters online for fairly cheap. I'll check out some local stores, looks like I should be able to pick one up for around 50 bucks that is still decent quality.

That sounds a little easier than using a multimeter, I wasn't even sure if AC could be measured with a multimeter in the way you described. It's not convenient or real safe, but it's nice to know it can be done that way. Thanks for the advice on the clamp meter, that would be the best. I...

Hi Everyone, I'm new to the forum, this is a great place to dig around and do some reading. My first question is: I want to read the current draw (amps) of a 120V AC device (standard wall plug). I've worked with DC quite a bit but rarely with AC. Can I just probe the plug spades with a...
