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!

Oh whats the continuous assesment for chemistry and electricity? I heard our physics and chemistry experiments count towards 1e4 and 1e6 and as well as 1e9. Is this true? Anyone know what percent of 1e4/1e6 they count for? if its true.

Bridge said he wasn't allowed to say that 1E4 takes your labs into account, and that's all anyone got out of him on the subject.
Don't know about 1E6 but I don't see how they could...

but the 1e5 guy said every subject has to have continuous assesment. thats why he had the mock exam. damn Bridge.

Engineering labs count for a portion of most subjects.
It rewards students who make an effort with the CA during the year.

oh and another question. sorry bout these. You know the 30% pass in one subject rule. If you get 30% and dont have to repeat does that mean that that subject doesnt count towards you average mark for the year.

Lets say i get 30% in chemistry (likely). does that mean my average mark plummets? or do the marks from chemistry still go towards the year average?

Both. Your average mark plummets because your marks from chemistry go towards your average. Why would it be any other way?

Can anyone still log onto wiley? I think it's been reset...

sorry, wasnt clear. i meant do you get 0 towards your average for the exam because technically you failed it? or do you get 30% towards it?

Boston

30% also note, you must average a pass. In other words, if you score 30% in one subject and 40% in the rest, you'll still fail the year as your average mark with be a fail.

Yep it's grand now, it was acting really funny earlier though, there were no assignments and when I logged out and tried to log in again i couldn't.

This crazy 1E8 exam that they've gone and changed the format of, does this mean there's no mcq part at all? How many questions will we have to answer now?

Birdie

2 from David Taylor
2 from Anil Kokaram
2 from Khursir Ahmad
1 from Alexis Donnelly

pick 5

Not sure if I like it this way, was just getting the hang of the mech calculations!!

Brian

I think I'll do 2-1-2-0. Maybe 1-2-2-0. No way am I doing an essay.

Birdie

It's not a whole essay. he asks you to do a paragraph or something... I think there might be some quetions on the rules of UD. I dunno cause when there was 25 MCQs he had like 5 questions in that. I never done the essay so its out for me.
I reckon Ahmads 2 questions will be grand and Kokaram will have at least one nice question. deadly one about fingerprints last year. I dunno about the Mech ones. they'll either be very nice or very aweful. . . he's notes on Webct are nice though.

Peleus

i think ill do 2 from taylor 1 from anil and 2 from k ahmad. The only one i sorta know well is k ahmad. ill just try cram for the rest.

Brian

I thought I would study 1E6 today, but I just sort of slept instead. It's TOO SUMMERY DAMN IT

Jonathan

Is 1e6 still on sat this year?

Peleus

ye, ruined a perfectly good friday night.

Jonathan

We watched the match in the pav after. Good times.

devinejay

Good to know it's open, just yesterday we were trying to get a plan together for the match, we'll probably end up there,

Brian

Zhu tut ftw.

Sitting in the arts block eating lunch and people watching. Just overheard two students saying how they wish the chose a degree that mean something at the end and they had a definite profession.
'OMG.. I wish i chose a degree so that after four years I could come out and say I'm a dentist, or I'm an Engineer'!!

If I were to use a FIR filter with a mask of [1/2, 1/2, 1/2] on the columns of a matrix e.g
[1, 2, 3
4, 5, 6
7, 8, 9]
and assumed that all the entries around the matrix were 0, would the first entry in the filtered matrix be
(1/2 x 0)+(1/2 x 1)+(1/2 x 2)

? The row ones are fine, but I've no idea what to do with the columns.
EDIT: figured it out. Was trying to do kokaram's q from 2005, the one where he says "and then along the columns". Realised he was talking about the matrix got from using the filter along the rows, not the matrix you had to start with. Was going crazy trying to figure out where he was getting his crazy values.

Peleus

what was the story with the first question on 1e8 exam. It was something like list three ways that a car can be run by nucleur power. I said a nucleur reactor and steam engine in the car (lol), chargin batteries with nucleur power and running the car off those and then using nucleur power to create hydrogen fuel to run the car. Any marks for those?

and the things that limit the max running speed of an engine, i said the stroke length and the mass of the piston and connector rod. that right?

devinejay

I said pretty much the same, except I mentioned that the Doc got shot by arabs when he tried putting a nuclear reactor in his DeLorean, and it probably wasn't a great idea.

I said the weight of the components and the compression ratio, I'd say you're right about stroke length.

I just drew a rotary engine for 1(b). Fuckawesome.

For 1(a) - Nuclear power plant providing electricity for batteries of electric car; source of electricity for electrolysis, ie Hydrogen Fuel Cell; Mini nuclear reactor (I had seriously run out of ideas).

for (c) I made it up. Piston ring wear and the max speed of fuel injection.

devinejay

I had a funny feeling you would have some way of working in the wankel.

Jonathan

A nuclear powered sterling engine. :pac:
