5. Hi
Ive been stuck on this question for days! its an edexcel M1 question from chapter 4 mixed exercises. Its question 21 (and 22 is also similar)
I would be so thankful if anyone could help me answer it - im so stuck, it depresses me.
The question is:

21) A light inextensible string passes over a smooth peg, and it attached at one end to a particle of mass m kg and at the other end to a ring also of mass m kg. The ring is threaded on a rough vertical wire. The system is in limiting equilibrium with part of the string between the ring and the peg making an angle of 60degrees with the vertical wire.
Calculate the coefficient of friction between the ring and the wire, giving your answer to three significant figures.

(answer at the back of the book = 0.577)

How do i answer this question? #

any help would be much appreciated
6. cool thanks..
7. If you need any solution banks:

http://www.sci2.co.uk/maths.html

My site has them so that you don't need to download them you can view them directly in the browser, for some reason the solution banks only truly work if you use internet explorer (The part of the software which shows you how to find the solutions).

The book can be viewed in any browser however.
8. Hi
