Based on the difficulty of the paper, maybe high 70's to low 80's. Again, scaling is all eshed this year so it's hard to tell

Really !? That high I was thinking 72 lol

In atar calculators do I put the raw mark in, or the mark you gave me ie ~76

You over thought the question. It was single shear, and you don't use the area of a cylinder, just a circle.
The diameter is 9.4 or 9.5, can't remember exactly but we confirmed it with our teacher.

Oh ok, thats good. Oh yeah I'm over analysing. Shear is parallel to the forces which would be in the plane of the circle. LOL.

Thanks for your response!

Also good to know that it was just single shear.

Does bournoulli's principle have anything to do with flight or is it just hydraulics? I was thinking pressure and stuff so I might've referenced it in the drone question...

The 76. Again, my estimate might be off as scaling is eshed. If you want a range, I reckon 73-78

Anyone have a copy of the paper?

Just btw astroman if you haven't found this already BOSTES just uploaded the paper I think either today or yesterday:

Just in case you haven't found it yet. You did HSC engineering studies last year right?

Flight. I did to

In 2013 an 80 raw got a 95 and someone got a SR with 96, 2014 i know for a fact 84 raw got a SR, though 2015 not sure and this year as well was much easier so who knows

2014 paper was much harder than 2015 or 2016 paper

Drone i was pretty sure you talk about the difference in air pressure caused by propellers, you could explain it in terms of Bernoullis principle and his formulae but i dont think it was necessary

I think mentioning Newtons Third law was critical for that question.
