I heard b6 cutoff is usually 78-84 depending on year, but this test was exceedingly hard it seems, id hazard a guess at maybe 76 raw but im a noob at this, thoughts people?

 

[dannyfisher2008]

also any idea for b5 cutoff? me/my class got superbly raped

I got 8.9 kN... doesn't give me faith that the units were in Newtons though

got that aswell i noticed the N so i made it 8900 N

i chose engineering studies in year 10 for prelim and it didnt even run at my school teacher left apparently

Should have done distance ed. Paid off pretty well I think

So im studying for this test, i figure, should put more emphasis into the older stuff we learnt, cause we just did aeronautics, ill remember it.

80% of the paper was aeronautics fml

 

[SoopaMario1]

^ so true... wtf most of it was aeronautics.
My teacher is a nice guy really, but he hardly taught us anything.
He told us interesting stories, but 90% of what I learnt I taught myself. (trusses, stresses, moments, shear, casting, testing ect.) and then, most of the stuff I spent ages teaching myself, wasn't even in the test.

how were you supposed to do the bus stopping force question?
I think i did something like calculating its KE, and using that as W, making P=KE/t

How about the stopping distance?

D= S x T

 

[machine2035]

D= S x T

Isn't that just going to tell you how far you will go at 60hm/h for 45seconds.

 

[Nws m8]

Isn't that just going to tell you how far you will go at 60hm/h for 45seconds.

Then you subtract it from original distance you downer

 

[Life4Never]

Then you subtract it from original distance you downer

Sorry to say this but that assumes that the truck moves at 60km/h the whole time. Stopping means decelerating to 0

I believe we got force of brakes above.

Fs= 0.5mv^2
s= 0.5mv^2 /F

answer was around 45ish metres. My memory is a bit dodgey.

That's was what I was getting at, but im a downer apparently hehe

LOL, I don't even do ES, lol I dropped in year 12 coz I did MX2 (thank God!) hahaha

Shouldn't you be studying for 3U instead of trolling people?

3u is nothing for a 4u kid

 

[Heydosaurus]

Your arrogance is astounding.

Yeah, that definitely seems to ring a bell. I'm glad that I seem to be making a massive improvement over my trial results in terms of mechanics, haha. In the trial, I think that I ended up with something ridiculous like 4/27 marks for mechanics. I thought that it'd be a funny idea to ignore my teacher whilst we learned the mechanics content in class and then not bother to learn it leading up to the trials.

That test.. went so badddd. Whats a fair b5 estimate??

 

[captainplanet7]

i think i crossed mine out cos 360 seemed to fast. thoguht i mase some huge mistake... fark.

yeah unrealistic answers are unfair. I did it like 3 times before i was satisfied.

that rings a bell for me too because i was like, ''its the same as the time from the question above?''

but yeah, that seems to be what i did too, thanks for sharing

This year's consensus amongst BOS, Facebook and my cohort seems to be that it was a pretty hard test compared to previous years. I would say that a band five might be somewhere in the early to mid sixties?
