Im pretty sure side BC is a true length on the top view since on that view it isnt on an angle and it is horizontal. Also i think DC is a true length on the front view since also it is horizontal in that view & not on an angle so therefore 2 true lengths B

PS How is the VR 4 in relation to the ropes and without distances

Tru but still think the 1st one is the right one but anyways

Personally to me I’d rather have the 1st one as it’s easier but I couldn’t care less tbh as the formulas are still there and if u don’t know which formula your looking for then u haven’t really studied so doesn’t really change for me

Me neither lol me neither lol but I still thing the one with the headings is the right one the 1st one

Also i think it is being confused with this one https://syllabus.nesa.nsw.edu.au/assets/physics_stage_6/files/physics-formulae-sheet-data-sheet-periodic-table-hsc-exams-2019.pdf which is the 2nd one posted i dont know why that one is up there

Yes that 100% is the new formula sheet

I get it but I don’t really get the velocity ratio part how is there 4 cut ropes and how do I just find them in general for a pulley system(VR)??

Anyone

I have another question about the pulley I posted it just now

How is the answer C????

How is it C????

Why is the answer B?? Thanks

How is the answer B??

Nah this explanation is really good thanks heaps I get it now!

Ok got it but I thought the formula has yield stress in it and max stress not allowable and max allowable. Max allowable stress equals yield/FoS

But isn’t the max stress 800MPa not 400

Is anyone working it out just let me know pls thx

I added the question

How is the answer 2000kg?? For Q. 9
