I'm currently going with some of the work on Heathrow T5 https://i.pinimg.com/originals/68/c8/c8/68c8c8b0cc9cddc10bddacb2c915f68a.jpg

If I had a source of heated water to feed it, how large could I make one that would run off of it?

Can it actually do any work on a large or small scale?

I assume it is terrible with efficiency. So would a thermoelectric generator do better?

Also if there is anything quirky or weird about how they run, or output, please let me know. I am just fascinated with them and would love to know more.

Hi All. I want to make a manual dump cart for my yard. I would like to have a crank at the front of the cart box, that when turned pulls a knee joint open. I can't find a source for the piece at the knee's joint. I believe I need a pillow block uniball with an acme threaded center...does anybody make this? Image coming in comments

I should clarify that I understand gear ratios and the use of compound gears to build a ratio, along with DMS of gear angle calculations. But I guess I need some guidance on how it all combines. I know you can't have half a tooth.

I am studying metrology and solidworks CAD programming so this would be really useful.

Sorry if these are really basic questions. I appreciate your advice.

Hypothetically, if you're in a country that has botched it's response to a new, deadly virus & hospital ventilators endup overwhelmed, how would sometime go about building a make-shift ventilator as a bid for last-chance life saving?

A global power grid would connect e.g. Europe, North America, and China together via high voltage wires in a way that any country could buy or sell energy to another country very easily. The intention would be that could be used to encourage zero-emission energy production and make it available to developing nations.

What are the technical challenges which would need to be solved before such a system could be created?

So starting off with a little background. I graduated this last summer with a degree in applied physics. I have been working at my first job for about 2 months now I know that later on I want to go into the engineering field. I know the three “main” engineering disciplines are software, electrical and mechanical.

I am most interested in electrical, followed by mechanical. So I really want to start self teaching myself everything about electrical engineering.

Does anyone know any good resources (other than YT) that would help me out here? Would it be worth getting any software certifications or maybe take the FE exam for electrical engineering later down the line?

The end goal is to get an engineering job at my next place of employment

Sorry for the rambling. Any information would be amazing! Thank you in advance!

Also side note: which engineering do you enjoy and what about it?

Never before have I seen a matter as glosed as this one is!

In some accounts of the workings of a liquid ring pump, the liquid ring is shown in the diagram having constant depth all round the circumference; in others it is shown deeper on the side towards the (eccentrically mounted) axis of the impellor, so that it actually adds to the depth to which the impellor blades are immersed in the liquid ring.

I thought I would look-round to find-out which diagram is the true (or tru-er ) one ... but I absolutely could not ! Every account I have been able to find utterly ignores this matter!

So I wondered whether any of the persons browsing or putting-in to this channel might know & be willing to say. I must be well-known which it is, as the shape of the ports must be contingent upon it!

I would have thought there'd be a video somewhere of one actually working with a transparent end-plate on ... but I can't find that !

For instance

#this

animation by Nash shows the ring as being thicker on the side the impellor's axis is toward, whereas the Graham MFG brochure

#here

shows a ring of constant depth.

Is there anyone who did studies in engineering then (s)he completed by studies in management I need someone to give answers of some questions there i have

I like almost want to step up the voltage of the 3rd and add in in parallel, but to act like a big capacitor to filter noise?

Anyway, I wanted a ic management solution or whatever thing.

Sorry if the question does not makes sense, english is not my first languaje.

I asked for a internship on a company. I had a resume on hand, but they only accepted a letter issued by my university. I'm a mechatronics engineer, my path focusing on automation. I learned a bit of robotics and other stuff, but automation is my prefered path and my ideal job. I asked for advice for it in this sub little time ago:

https://www.reddit.com/r/AskEngineers/comments/ecmrom/what_should_i_know_to_become_good_as_a_dcs/

What happened is, as mechatronics I'm be going to mine maintenance, rather than plant maintenance. The biggest difference being the machinery; i will be working on heavy duty machinery rather than, let's say, programming or instrumentation. The fault is mine, I didn't made clear enough what places I'd like to be in (those details were on my resume), and it's not only a preference, it's were I have more knowledge and experience.

I'm trying to be positive right now, even when at first, and for some minutes I was somewhat disencouraged and totally out of my confort zone. I can't really say I like or know about heavy duty machinery, I'm looking for as much information I can get before I'm going there... I'd like to force me to like this new path that lays beneath me, but don't know how. I will work my ass off, as usual, and maybe ask for a second internship this time in instrumentation or mechanical design... but that's very difficult for many reasons and right now I'm feeling like I lost an opportunity to work in the field I like the most, to work in a field I barely know (tho maybe it fells as a career path that I never though of).

Please, did you had some similar experience? or maybe a mindset to take the most of this situation?

I graduated in April with a ME degree. I never interned. I worked a restaurant job year round and coached in the summer. I’m now just coaching for the winter. I don’t know what to do to enhance my chances of being hired in my field. Also, how can I be more marketable? Any suggestions of what I should do will be greatly appreciated. Is it possible to get an internship at this point? I appreciate any help. Thank you in advance.

First "big boy" job out of college and have been here 6 months. Coming up on my first review of how I'm doing, accomplishments, what i need to work on, what path id like my career to head, and any questions I want to present etc.

Im wondering, would this be an appropriate time to ask for a raise? I'm a project/process/design engineer $60k with benefits. I feel like its a dont ask dont get kinda thing for raises. I have a ton of responsibility and in charge of doing a ton in which for the rest of the departments depend upon my work to conplete theirs. We are understaffed in my deparment (4 total) and were pumping out a ton of projects most of which are quick release.

I know i dont have engineering experience so i ask, when is it appropriate to ask for a raise?

Thanks for any input or help!

Settle a friendly debate, engineers of reddit. A .75 caliber Brown Bess, using 75 grams of FFg black powder to shove a 500gram bullet down a 47" barrel (just a smooth tube, no rifling to worry over). What kind of psi is generated behind that bullet?

After reading some papers, I have things I would like to ask or discuss, but do not know where to do it. Can you recommend me any website to do it?

I did a home renovation and trying to make the house my own. I hate this post. Do I have to destroy the drywall to see what is it actually supporting? Does anyone just know?

Denver, Co house built in 1983.

a 2x4 is on each side of the switch.

Was thinking of just cutting the dang thing and putting a 2x2 thick steel square tube to support it.

I'm trying to design the of the hook-up of 2 690V motors on a skid to an outlet.

The running current of the motors is 8A and the starting current is 68A. The length of the cable is approximately 50m to reach the outlet. It takes a 5 pin 690V plug.

Can anyone give me any advice on how to go about sizing the required cable? I'm not an electrical engineer by trade so any and all advice would be much appreciated.

Thank you in advance!

Not sure if this is the right place to ask, but I'm looking for small volume 60mm OD, 3mm wall aluminum tubing for a project, and I can't seem to find anything over 50mm OD online anywhere.

Does anyone know where I might be able to find this type of tubing?

Any one willing to help with engr 103 assignments. I need to get contact information from 5 mechanical engineers so that I may ask questions at later time about being an engineer. First have to submit contact information to my instructor first.

Can anyone explain how the mechanism inside this makeup pen works? Push top ratchet? If anyone could refer me to a cross-section that would be so helpful.

Hey guys,

​

I'm looking for charger for my 12V 70Ah battery, although I don't want to spend any more than £30 (UK based).

I've found this although i'm skeptical considering how much cheaper/smaller it is than the rest that are available.

Do you think this one is acceptable or do you have any better suggestions?

Cheers.

Hi everyone,

I designed the following coil with the help of Coil Designer TI WEBENCH

• Outer Diameter (Dout): 40 mm
• Number of Layers: 2
• Turns per layer: 35
• Trace width (W): 0.2 mm
• Spacing between Traces (S): 0.2 mm
• Inner Diameter (Din): 12 mm
• Space between 1st layer and 2ndlayer(x12) = 1.5 mm

This gave me L=94.8 uH, but after fabrication and measurements, it always gives me 4 uH. 

Any help?
