Her answer was similar to one that could be found in a multitude of text books... and your reply sounded as if she had explained the meaning of life in one sentence, in which case I can understand "bowing". If it was an answer to a hard question, I could understand your reply, but alas it was...

Umm. Not really. I have built several electric motors that have worked in a USEFUL fashion - ie can have a load applied such as a fan. I can tell you that Al foil will wear through very quickly on a motor that is decent. If it spins very slowly and isnt required to work for very long, sure use...

I got full on this question. I said about creating semiconductors and electrical power.

Jacaranda has soooo much irrelecant bullshit. Excel isnt hard enough. What I do reccomend is getting several different textbooks as well as the "Success One" physics book which is full of exam style questions.

Nope. Got 97% in our trial <gloat> ;)

You dont want the standards, you want a little drawing guide book. as above ^^

Maths is a tool, and engineers use it to solve problems. Engineers are problem solvers. IF you dont like solving problems, dont do engineering.

Look. Its like the car industry: Ford or Holden? Ok, statistically, Holden have one the Bathurst way more times that Ford, but the Fords have higher build quality and cheaper spare parts. However, you cant go wrong with an XR8 or SS. I really dont think there is that much difference. I will be...

Basically, as long as you include all the essential features and have close enough resemblance to the right dimensions, you will be fine. They understand that its freehand and if its a little wobbly they wont care. If you cant draw a straight line with out a ruler, buy a ruler.

UNSW or UTS? - whichever offers me a COOP scholarship ;) . Sort out your differences with a back alley knife fight

Not mine - hes great. However the year below us, a different teacher is taking them and they all feel the same way as you.

I got 92%. Came 1st overall :) (at my school of course - not the state ;)

How is the UTS COOP engineering scholarship?

40%? I thought there was a shortage of engineers? Just because you get a degree in mechatronics or whatnot doenst mean you cant get a job as something else.... Also, I come from a public selective school - i have made many friends from other schools. Perhaps the "us and them" relates more to...

Why would you put molbdynum in an aircraft? Surely you said Aluminium/molybdynum alloy? Molybdynum in a pure state is terrible for anything....

*are there any not "is there any"

http://en.wikipedia.org/wiki/Neutron_scattering Basically, you shoot neutrons at a target nucleus, they bounce off and you can calculate the structure of the nucleus. De broglie - everything with momentum has wavelength, and thus can be diffracted etc.

Its really not that hard..... but anyway

Dont bother using carbon brushes: a) If you have a crappy, homemade commutator, the carbon will flake off and fill the gaps in the commutator, short circuiting the motor. b) The friction difference between metal strips is so minimal that its not funny Also, dont use Al foil for anything...

Please dont become an engineer:rofl:
