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.

[ardei]

72%

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

[Auslandau]

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.

Exact same here, I know now though.

[asusdragon]

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

[Casper]

72%. Pulleys and electrical stuff kill me.

Hahahaha ... that was the same for me as well.
And the same score too

[Interceptor]

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

[JOSH]

well i got 81% just scaped in.

[Walkinshaw]

94%. I guess Engineering paid off.

[Walkinshaw]

delete please

[mik]

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

[Chippar]

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

[Fairlane]

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

[HLC]

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

[mik]

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?

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.

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%.

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.

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).

Thats what I thought too.

No such thing as "suction" just high and low pressure. The high pressure forces it's way into the low pressure.

Same with temperature. There is no such thing as cold, only heat or high and low temperature. You don't cool something, you remove the heat.

I think I buggered up all of the pulley questions. I don't remember even studying pulleys, and I've pretty much forgotten all the rest in the last 5 years too. Wow I guess that degree was a waste of 20 grand :

So basically its because of this, damn this will show peoples age.



So my take now is that it is very technical difference, but scientifically correct. Tests usually require the most correct answer to demonstrate the extent of knowledge, rather than one correct option among 3 pretty well wrong ones. Most good multiple choice tests will give you two choices that are close, but only one is technically correct.

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...

[THORNSPAWN]

88% there were a few I just guessed.

[Yellow_Festiva]

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.

Same score, similar situation. I bludged at the back of the classroom until the end of year 11. hehe

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