Hi, I read that students in the HSC who achieve an ATAR of 98+ receive an offer into advanced engineering, however II just missed this mark. I am very keen on getting in, I was wondering if there was a way i could still go advanced engineering?
Cheers
in a motor back emf increases as the motor spins faster. when back emf = supply emf, the motor spins as constant speed... and since no work is being done. it is therefore C.
yes multiple choice has been tricky this year. i probably got 14 wrong then hahaha.
for 19 i got the same as you, i assumed that 'low' resistance would cause minimal heating haha.
4. B: higher altitude to lower is a loss in gpe so negative? (not too sure)
11. C: law of conservation
14: B: initial change in flux is positive gradient hence induced emf is initially positive
16: C: ideal motor no energy lost hence back emf = supply for constant rate
18: C: force is given...
for 10: you know what, looking back at my MCQ paper, I did it graphically and it would've been right if I only drew in the force P horizontally. Instead I accidentally drew it in parallel to the plane, thus I had a reduced answer. Pretty sad.
I can only advise you to do some engineering past paper questions involving calculations. Calculations are a major part of the examination and are easy to scab marks off, even if your final answer is wrong.
Make sure you can relate a question to a formula on the formula sheet on the back of...
definitely not, sorry. everyone i've seen has gotten a copy from their respective schools. if you cannot get a copy from your school today, you'll have to work off Excel Engineering or another textbook.
It covers everything. Chapters: forces, power, truss analysis, stress/strain and so on, all that's in the syllabus and a little beyond... it has good examples/explanations as well as plentiful questions.
I've been told that a typical band 6 cut-off is at around 83-85, of course this may vary from year to year like any other subject.
A quick glance at your ranks shows that you're clearly on your way to beyond a 95 ATAR.
The past three years have seen a question on digital logic. Assuming this trend continues, it seems they only examine simple knowledge of AND, OR and NOT gates.
Personally I found http://whatis.techtarget.com/definition/logic-gate-AND-OR-XOR-NOT-NAND-NOR-and-XNOR very helpful in...
