HSC Question help!! (1 Viewer)

[EpaX]

Hey everyone, there's this multiple choice question from the 2005 HSC (see link below) I was working on whose answers were completely off to my answer (which I'm almost certain is correct). I got F = 3502.8 N, whereas the board of studies answer was (D) F = 1751.4 N. What do you guys think?

I think you're wrong, I worked it out to be 1751.4 Newtons using the bending stress formula
