I said A, electrolytic reaction because B was worded as "stress corosion cracking" not "stress cracking corrosion"
I picked A as well :OI said A, electrolytic reaction because B was worded as "stress corosion cracking" not "stress cracking corrosion"
How did you Answer that one?about the self lubricating bearings
Gah... I got like 125/150 or something stupid.For the two different types of multiplexing i did: a) Three way phone call
b) Bandwith through multiple computers
and yea... the fuckin pictorial picture ..... took up like the whole page, still pretty confident i got full or close to full marks for it.
I had trouble with the bicycle velocity ratio one though
Yeah they sound like mine lolSome random answers off the top of my head
For the one with escalator with 115kg on it, answer was 414W I think.
I got 40 something mm for the extension of the cable in the last question.
Question about the current in the circuit with the lightbulb I got 2.5mA.
Any of these answers ring a bell with anyone else?

Do u remember what the values were for the extension question?Damit (@ the brass thing)
@ above, I used V=IR and plugged in whatever they told us. Though I may (likely) have used the wrong voltage value.
Nah man it's just mgh/t as there was no frictioni got 1008 W, its sq route of 20squared + 9squared to find displacement, then displacement times force, 1150N then divide by25 seconds to get power, i got 2.5mA and 43.23mm extension, hopefully thats right :S
No, but I got something close to that for the power loss of the battery or something? Might not been a battery.. i dont remember lol.. power loss of something.... whatever it was used for xD mighta been a bike, don't remember.damn, 9/10 for me too did anyone get .1388888 for VR of the bike?
8M length... 111 for the modulus ... 0.5mm^2 and 300N I THINK.Do u remember what the values were for the extension question?
