anything like that? if so just do 1.5*0.12=0.2*X so X=1.5*0.12/0.2 =0.9 Nm
but hey i dont know what the exact question was cos i didn't sit this paper, this was just a guess at what the question might be?
Swap the pivot and the force and you're done. You had also the force in the middle was 1.5N and you had to work out the furthest left one. I think i got 0.9N
lol peak, it wasn't as hard as you are making out; if you slept well and revised there's no excuse to get below 51-54, hence the grade bounadries will remain i think at 44 or 46
No, the grade boundaries can vary quite a lot for this unit. I took the 2013 past paper last night, and I thought that paper wasn't much harder than the one this year. To get an A* in that paper you only needed 41. So you'll probably need 42-43 for an A* in this year's paper.

oh ok well it doesnt actually effect it and yes the answer is 0.9N lol just realised i put the wrong units Nm in my original post because i was still trying to figure out what the question was while solving it , 0.9N should be correct
