1. Edexcel M2 June 2009 Q4b
On 4b, I don't understand why the horizontal force exerted on the rod is 44.1 and not -44.1. I calculated the horizontal component of the thrust as Tcos45 or 44.1N to the right, so shouldn't the reaction at the hinge be 44.1N to the left?

Can you post the whole question? I for one don't have access to that paper.

Yeah, I'd agree with you. On the horizontal bit at least

Can anyone else help? The exam is on Thursday and I still don't understand why the mark scheme says that.

It's possible the mark scheme's wrong, that there's a typo or the question was misread. Is it the official markscheme or one a teacher rustled up?

Are you getting similar questions in other papers (and textbook) right? If so, I would say you don't have anything to worry about (at least, in regards to that type of question ).

I checked the Edexcel mark scheme and that's what it said. I'll post this in the M2 revision thread and see if anyone else can help.
