How'd everyone go? (3 Viewers)

How'd everyone go about finding 'X' in the truss. Method of sections? sum of vertical forces?

 

[alen180sx]

Nah mate, 2.5mA

How?

^i got 20ma too but im fairly sure we are wrong. It was a really basic quiestion but i think we overcomplicated it. It just seemed to simple for the 2 marks in my opinion. Though that test was quite the fucking challenge

 

[SnowTau]

How?

Voltage drop was 16 not 2.

 

[alen180sx]

Voltage drop was 16 not 2.

Oh shit was it, my bad then.

 

[mathysbouma]

shit
was the hardest engineering test and i expected to roll engineering with a few hours the night before.

 

[SnowTau]

Yeah, I see what you did though. They tried to over complicate it on you. What it actually said was the voltage recorded after the light bulb was 2, not the voltage drop over the light bulb, hence the actual drop was 16V, simple question presented in a more complicated way.

Oh ok thanks man.

I got some where in the 20kN's... I think 24.5 but I'm not sure. seems a bit unreasonable.

 

[ben_carroll93]

yeh i got like 2 or something. it seemed right because there was a 15kn up and down and i figured they'd cancel and that a small force would be reasonable

Nah if you check last page I even redid the calculation to check, 24.5 KN in compression

I've done A LOT of that stuff (huge assignment based around building a bridge) so I'm pretty confident in my answer.

 

[AAEldar]

I didn't enjoy it...

I do enjoy it being over though

 

[megabakedpotato]

can't remember what I got tbh haha


Would anyone like to speculate what they reckon the band 6 Raw mark cutoff will be?

 

[jonahpetrie]

that was a difficult exam. Having done the ones from the past 10 years, this one was pretty rough. I'm assuming since last years was about 83, this year might be a bit lower. Im probably wrong though

 

[taeyang]

I didn't even get an answer for the BM diagram.... as well as the my first drawing being an absolute pile of garbage... I'm hoping for at MAX 60 raw

I rubbed that out and redrew it like 3-4 times... the drawing we had to get it from was ridiculous... so hard to tell where everything was and what was happening... I didn't get it.

I'm with you there, the drawings were so.. ugh. Rubbed mine out a few times hahaha.

 

[SnowTau]

My stupid table had something loose on it somewhere, so everytime I rubbed it made a loud banging noise, and I felt bad for everyone else sitting near me haha, it sucked. At least there was only 7 of us there today, small class.

 

[annnna]

Considering how i did minimum study, (no joke) it wasnt actually that bad. Like compared to last years paper especially.
But yeah, i was shitting myself more before the exam because i thought it was gonna rape me. I just want a pass tbh!

 

[Weasel406]

I've never really got a bending moment diagram wrong until today. I had never seen one like that before.
