Engineering Thread

Brian

We really should have our own forum entirely, but I think a thread'll do.

I rather enjoy the relaxed nature of a thread derailment, but in the general public's interest, maybe we should all hang out here.



tl;dr TR032 ARE GO!

Fad

Here you go THE ENGINEERING FORUM NOW BOG OFF

Brian

Erm, I meant the TCD Engineers. Curious as to how you came across this thread

mathew

YAY.. engineering

Brian

When's the mini meet?

Kurtosis

You could go for a large catch-all Engineering thread akin to the BESS thread. You get the glory of starting a big massive popular thread.

bit of a bogey

Hi, can anyone help? Im tring to select the correct motor. The motor simply has to pull a weight of 2kg. How would I calculate the required torque? The speed isint important but It probally comes into calulations somewhere? Does it relate to the torque?

Boston

I really hate large catch all threads. Anything of relevance gets lost. compartmentalising things is betters. That said, baza should learn to stay on topic!.

Jonathan

We all go off topic.. It is in our nature..

And woo for the thread. :pac:

Whats it for exactly?

Second year buggy project by the sounds of it.

That caught on quicker than expected.

What is the coefficient of friction between the mass and the surface?

Brian

Erm, that person just registered. Thought I'd point that out.

Boston - yeah, I don't like all-in threads, but noone else seemed to be starting one and it seemed to be a necessity.

We havnt got anywhere near that yet.
Only doing the bridge now, the Buggy isnt till after Christmas. we hanvt been told anything about it at all...

Thank you.. Posting off m.boards all night so i cant really see whats going on.. Hence calling for an official engineering thread about 10mins after you started one.

Boston

Ok, once everything even remotely engineering related doesn't end up in here. keep this for miscellaneous crap.

What was that about phone interweb being better? :P

Edit: Are you using Fennec?

That explains why the person doesn't know how to calculate the required torque.

A thread dedicated for the random offtopic crap that ends up in seemingly every Engineering thread, you say?

Of course, such a thing wouldn't be necessary if people understood the concept and benefits of staying on topic.

Brian

You're just jealous because you have no TP buddies go to OT with ;P

PurpleFistMixer

Indeed. I am so very ronery.

Nothing to do with my mod-related dislike of threads going off topic, and the subsequent cleaning up that must be done to put some semblance of order back on the place.

A phone is better in a lecture where laptops are not permitted.

I prefer my wsxga+ screen to this qvga yoke.

Fennec?

It's always like this at the start. A huge degree of off topic posting until people settle down. Think of it as something to keep actually informative threads, like the error cal one, clean.

Wouldn't be a problem if you coaxed the admins into giving us our own forum. :P

And can you not hang out with myth? He did tp for a while.. Then joined the cool kids..;)

Brian

This is kind of cool..
If only windows would change the orientation of my trackpad too, to match the screen..



Ctrl + Alt + Arrow key, in case you were wondering.

Jonathan

You now have an oversized nintendo ds.

Brian

If only I could find a 10.2" touch screen for it.. and an Electronic Engineer who's maybe nearly got a PhD by now.. HEY!

PurpleFistMixer

Maybe we don't need an Engineering thread. We just need a Baza210's (pc/phone/whatever related) exploits thread. : p

Brian

My eyes hurt

So when is the Engineer Mini Meet, huh?

Jonathan

SF engineers are in till 6 on both wed and thurs so i propose one of those days.

Brian

I'm on the Luas!


Erm, I vote Thursday too, JFs are in until 5/6pm depending on group. Plus, I have Badminton Wednesday.

Yup, for first year myself and a few others were called 'TP Refugees' by some of the lecturers.

If you're thinking of organising a meet-up just do a main tcd boards beers and get engineers to go, and then just alienate everyone else who goes to it.

How many of ye moved?

We do that anyways.. just look at boards..

There were 3 of us who moved from TP to Engineering, and I know someone else who moved from Maths to Engineering a few months before.

Sorry I knew I sould have been more specific but in my defense I am new to this! The motor actaully needs to lift this weight if u get me. Imagine a standard dc motor is on a bench and needs to pull a 2kg weight up from the ground. How do I calculate the torque required. I then need to select the correct motor. But I do need to state my calcuations used! Any help would be great! Thanks!

mathew

what year/college are you in?
Is this an assignment you have?

bit of a bogey

Im not actually in TCD. I go to cork IT and its part of an ongoing project thats already due! Ive still alot to do n am under serious pressure!

T=F*D

where:
T = torque
F = force = mg = 19.62
D = distance

bit of a bogey

thanks jim but what distance do I use? Is it the radius of the motor shaft? Just say I am using some sort of leadscrew mechanism that is connected to the shaft. Does that change the distance that i will use?

uprooted shane

jasus gone for the weekend and i mis out on all this! damn!

yay mini meet!

mathew

Thats what you get for living down the country :P

Jonathan

So what day suits people?

mathew

Thursyday

Do you guys not meet every day in class anyway? : p

I'm tempted to go back to some first year lectures for the laugh actually.

Brian

Ah go on. I'll be the guy wearing the sudo make me a sandwich t-shirt.

Although apparently someone / a couple of guys in CS have the same t-shirt, so if they don't look super sexy then they're probably not me.

Hummm.. If i just stay in the joly after solids and structures.. You have elec and mag after..

Brian

Sweet, would you mind writing up my Physics lab too?

Real question - When does Mechanics stop being stuff I've done in Applied Maths and turn into something worth taking out my earphones for?
