Oh awesome thanks

Also was it meant to be going downwards (south east wards) if that makes any sense?

How many marks do you think I'll lose for Q6 getting the i and j vectors the wrong way around -with all correct working (all my values are slightly off)?

Anyone remember how many marks q5 part b was? Where we had to find the distance in that moments one?

Here are my model answers, with the actual questions. Let me know if you spot any mistakes.

How the hell did you get hold of the paper?
I expect to get 72, hopefully an A* with some margin to accommodate for any mistakes in other modules.

72 should be approx 95 UMS

What do you think the grade boundaries will be? 69 then for an A*?

I personally think it would be:
74 - 100 ums
67 - 90 ums
60 - 80 ums
etc

In any case, last year for FP1 I managed to get 95 UMS which was 72/75.
It was 62 for an A and 69 for an A* (90 ums)

Wow I didn't realise the first part of the statics question was worth 8 marks 0_0. How do they mark questions with i and ii? Do they combine the marks from both parts ie if I resolved forces (horizontally and vertically) in ii but you get given the mark in i. How many marks out of 8 would I get for the following? I took moments about B and got an expression for R in terms of d,g, theta and F. I then resolved upwards and got an expression for F by cancelling P. I had Psintheta=something and Pcostheta=something so divided to cancel P. I then found a fully correct expression for F in terms of d,g and theta but then I forgot to sub F back into R so I would then have R only in terms of d,g and theta. I checked at home if I were to sub in F and I would have gotten the correct expression. I realise now that taking moments at A would have been easier but will they give marks for my method (taking moments at B)? I had 3 correct equations with which I could cancel things to get P and R in terms of d,g and theta.

what do you think ill need for an E

37-39
