When you work your ass off for the past 1.5 years on 4u, doing heaps of past papers and having covered most exam style questions under the sun and averaging 90+ in most past papers. And then you go into the exam and nerves take over and you freeze.
1.5 years of working so that i can get 97+...
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.
Some sort of summation, possibly like the one from grammar 2016
I can't see it being probability though.
If they do plan on being cheeky, i can see a mechanics question like 2012 or a projectile motion.
Even though i hate easy tests as it doesn't differentiate between good students, i really hope the mx2 paper is doable (like last years) or atleast has questions that i've already done before, for the sake of my atar.

2013 paper was considered difficult and hence it scaled high. Again, 96+ is needed for SR and to get that, you probs need at least 92-93 raw (considering the difficulty of the 2016 exam).
Lets the roots be alpha and 1/alpha.
Using product of roots, the alphas cancel out and your left with: 1 = 2n +1 / n- 2
Rearranging for n, and you get n = -3
