What was the answer C? Like what did option C say? I forget hahaha

That was so damn easy. Its scaring me to think how the BOS can give us such a shit hard paper in maths, then this :L

Found it a fairly easy exam, had no clue what a virus signature was, took a guess and got it right :D

You reckon? :S The theory I found alright, but the marks for mathematical stuff was crap lo

I feel more anally penetrated after that test, then when I did the Engineering Studies test...

Nah just maths lol, I've always done it, and never been an issue before, of course that was teachers hand marking it..

So I did my test in pencil, and the supervising lady only told me later on as she walked past me. She didn't give instruction on us using pen's so yeah... What's the procedure if I have used pencil? Will they still mark it? or..? :/

Our teacher never even taught us anything about brushed and brushless DC motors :(

Re: Did poorly in engineering exam yeah same, i just made up some equations and somehow made it fit in an attempt to fish for marks :L

Re: Did poorly in engineering exam what was the hardest question for you guys? :/

Yeeeeeah smashed that exam. Gunning for a band 2! -.-

hahaha true that :L And i think you uploaded the question twice..

yeah im on the same boat dude, dont even worry :L

All good :) tbh with you i dont know :L it looked like it so i just had a guess haha

Shear Stress= Force/Cross-Sectional Area therefore: 150x10^3/50x5 (its 50 because the length of the punch is 25, and thats half the length the plate) =600MPa then: 600MPa/2 (divided by two because the punch is half the plate as above ^ in brackets) =300MPa :)

practice, practice, practice!

for 13 I got D 300MPa :)

Just wanted to wish everyone all the best for their HSC in 2013, and hope you achieve whatever your goal mark may be. I'm hoping for a state rank more than anything and I hope I can get it :)

ahhhh I see! Was wondering what those dashed lines at the bottom were.. That's alright, no need to draw it, you've done enough! It helped plenty Thankyou!

Hey guys, just wondering if anyone could give me a hand with this question in the 2013 Specimen exam paper. I'm usually really good with pictorial drawings, but this one has me really confused :S All help is appreciated! Thankyou! :)
