80% - I lost nearly all the marks in the pulleys ones, I flew through the electronics though.

i got 1-14 correct then i got bored and guessed the rest without reading the q, i got 50% :/

You score 76%

I feel so stupid!

also

I dont have a clue about pulleys, plus I was annoyed about the consistent miss naming of forces and weights

50Kg or 50Kn is the same thing (as long as the 50kg is one metre from the fulcrum of course)

No, 50kg is ~500N (depending how precise you want to be with mavity), and it is asking for force, not torque/moment, which is what you are describing. Torque/Moment is measured in Nm, not N.

but it is totally different notation, kg is not a force, its a mass, N (kgm/s²) is a force, Nm is a moment
The same as 100kg is not a weight, it's still a mass, weight is a force

I know, I made that point initially, I was just correcting the appropriately named 'nokinidea'.

Yea, I was too, I just took a long time posting

58%, which is pretty bad. I seemed to get chunks all right or chunks all wrong. I'm sure that says that I'm completely lacking in certain areas (ie. scientific knowledge beyond basic deduction!).

Clarkey · 26 Oct 2007 at 02:28

84%, not too bad.

yantorsen · 26 Oct 2007 at 02:32

I got 70%, but then I am only 16 =/

Question 44 is weird. I disagree with their answer.

NightSt@lk3r · 26 Oct 2007 at 06:40

i got them all right upto question 10 but couldnt be botherd to go any further.

GravyMonster · 26 Oct 2007 at 10:04

74%

I got most right, but all the ones about forces and weights screwed me over. Must have been off sick when they taught that at school

I got bored after 11. Only got 7 wrong though.
