Oh dear, i put 37.2 kgm^2, not looking good for me What moment of inertia formula did you use?
I initially had that, it wasn't your formula, the problem was that you used 66kg instead of 33kg for both the "rods". Since they were equal masses and his overall mass was 66kg...

In any case: I=(1/3)mL^2, i think it was.
If what the above person is saying i wouldnt worry about it, at most it'll be 1 mark dropped... probably half a mark tbh. They're nice when you make small transcription errors in physics

Yeah thats exactly what i did Hopefully ill still get some marks...
I got 0.043 N for the tension but my direction is wrong i think.
Oh good, well at least my tension is the same as yours ... for direction i put '24degrees to the right from the original position of the sphere', but i have no clue if its right...
If Marcus and the added changes are correct then I'm standing in around 74-80%... Not bad, but did the worst thing in Qu 8biii) where I did the working on my calculator, got it right, but didn't put it down in paper! :/
