I think that Q10 should be B because they are asking for the mass instead of the weight force, here's what I did

Here's what I had for MCQ: 1. B 11. D (actual answer is C) 2. D 12. D 3. C 13. C 4. B 14. B 5. C 15. B 6. D 16. D 7. A 17. D (probably C) 8. B 18. A 9. D 19. C 10. B 20. A

I think that B is right for 15, since the most appropriate one would be malleability and ductility is directly proportional to that

Pretty sure its 13 right? I did sum of the forces parallel to the plane = 0, maybe you didn't divide by the acceleration, I had the same answers for the ones in section 2 tho

I found it pretty straightforward overall

The band 6 cutoff for externals is around ~81 raw I think

Use for area of a circle since 95% of the time they are going to give diameters and not radius Most of the time if they give you a number in the question expect to use it to work out the answer (or it may lead you to a easier working) Write any relevant working down, that includes the...

yeah looks good

I think of it as two smaller simple machines, the pedal/wheel (VR_1) and the chain drive (VR_2) VR_1 = de/dl = (2pi x effective length of pedal)/(pi x diameter of wheel) [1 rev. of each/circumference] VR_2 = driven on driver [very useful to know for gear/drives] =...

Even though we got English up ahead first, I suggest cramming these topics for Engo first on Wednesday if you think you are cooked Mechanics: Trusses, SFD, BMD, moment, stresses (tensile, compressive, (double) shear, punching, P=F/A), converting forces to parallel and perpendicular to solve...

Yeah, tho not often since it only came up twice since the new syllabus, but since its engineering so you never know when it could come up again so it wont hurt to know. This formula is used for pressure in any kind of fluid, P_o is the external pressure, p is the density of fluid (use 1000 for...

Didn't know there was a dedicated place to make these threads before I made mine, oops I also think there would be a bit more mechanics questions this year. Also, is the general consensus that the engineering HSC has gotten a bit easier over the years? Dunno why tho since they all run on the...

I think there's gonna be more marks on drawing this year since last year didn't have as much of that as 2022 and 2021, Anything you guys have in mind?

Every drawing question from 2001 HSC onwards are good practice I'd say, the more you do the better you get
