You can review the right and wrong answers at the end of the test by clicking on the magnifying glass image, it shows where you were right and wrong.

72%

Thanks for that though, was good revision for HSC Engineering Studies exam in two weeks!

Auslandau · 02-10-2007, 10:53 PM

60% .... There is a reason I have a mechanic!

i got 58%.
electronics/electricals i have never comprehended.
there were a couple of other things there i have never had the need to know either.
thats my excuse.

asusdragon · 02-10-2007, 10:56 PM

well i got 74% still a fail but hey i not complaining to much. though i dont understand how some of thats works

Casper · 02-10-2007, 10:57 PM

72%. Pulleys and electrical stuff kill me.

Interceptor · 02-10-2007, 10:57 PM

86%....... shouldnt do it when you're tired

Walkinshaw · 02-10-2007, 11:20 PM

94%. I guess Engineering paid off.

JOSH · 02-10-2007, 11:21 PM

well i got 81% just scaped in.

Walkinshaw · 02-10-2007, 11:25 PM

delete please

mik · 02-10-2007, 11:36 PM

dam thats a good test for a dumb old fart, passed but only just 80%

Chippar · 02-10-2007, 11:39 PM

72%......could only guess at the electrical wiring terms

Fairlane · 02-10-2007, 11:42 PM

66% man i used to get A's in Physics. Boy ive forgotten a lot.

mik · 02-10-2007, 11:46 PM

one question seems wrong to me no.48 does the cylander fill due to atmospheric pressure or due to piston sucking it in :( i got that one wrong.....i put sucking any one disagree /agree?

Exact same here, I know now though.

THORNSPAWN · 02-10-2007, 11:55 PM

88% there were a few I just guessed.

When the piston moves down the cylinder, what happens? The pressure inside the cylinder is lower than atmospheric. So the "weight" of the atmosphere above the cylinder forces air inside the cylinder.

HLC · 03-10-2007, 12:00 AM

72% some of the forces stuff with the pulleys i just rushed through. the rest was alright

Yellow_Festiva · 03-10-2007, 12:01 AM

80%... yay.

Not bad for a person who dropped out of physics after 2 weeks in yr 11.

Ok, but I also taught "Simple Machines" term 2, and electronics term 3 lol.

cheers mate

Scott · 03-10-2007, 12:11 AM

81% - scraped a pass together, better stick to my day job.

It fills because the pressure inside the cylinder is lower, therefore the air pressure forces air in. I know that's a pretty poor explanation but that's how it is.

God damn not counting those stupid divisions on the see-saw balances correctly. woulda got 100% otherwise...96%
...would hope so after at the end of a 4 year engineering degree...

Is that a very technical difference though? I mean there would be suction too effectively? A syringe for example would be from the suction yes?

I got that wrong too, and well a few others. 66%.

BadMac · 03-10-2007, 06:21 AM

100%, I guess all those years of study and a degree paid off.

Also Question 26, the answer is not correct (I have come across this before, so knew what they wanted). In circuit theory they teach that power takes the path of least resitance hence 2 lights (loads), in reality electricity flows according to resistance, the circuit with no load has resistance, the circuit with load also has resistance, the power flows in proporation to the resistance, so some power will go through the load, I have done this experiment to prove it and given sufficiant power the light will glow, although the other circuit will get hot due to the amount of current flowing through it.

As a second explantion, the switch circuit could be constructed to be the same resistance from an electrical perspective in which case the current would flow equally. But anyway choose there answer else you will get it wrong with no right of appeal.

xbcool · 03-10-2007, 07:03 AM

80% mechanical questions were pretty easy and fluked a couple of electrical questions

XC GXL · 03-10-2007, 07:19 AM

Good site and some interesting questions especially the electrical ones (I don't understand electrickery).
I managed 98%

I would be disapointed if I failed as I am a consultant project engineer (mechanical).

Scareybear · 03-10-2007, 07:25 AM

86% the pulley stuff killed me :(

TruBlu351 · 03-10-2007, 07:56 AM

Jagged a 92 and a few grey hairs worse off ;)

aquahead2001 · 03-10-2007, 09:12 AM

92%

Interesting to check what I got wrong. Shouldn't rush, I guess!

soulfire · 03-10-2007, 09:23 AM

lol i only got 62%... high school phsyics feels so far away.
