i just remembered something about the multiple choice question using bending moments and second moment of area. i got an answer which was of the same numerical value to part d, but it was like 6 decimal points out, is second moment of area meant to be to the power of negative 6? i cant remember entirely, but yeah, anyone alse notice anything about that question at all?

The answer was correct, your working wasn't. You had to take into account that the second moment of inertia was given in mm4 and therefore you times the initial moment which was 10^6 by 10^-12 to bring it to metres and thus giving the 10^-6 which you would use. You just got lucky they didn't give the huge answer ebcause that may have tricked a lot of people.
