# Mechanics 2 MEI June 06 stuck watch

1. Currently stuck on this last part of the question on June 2006 Mei M2 where the answer is apparently 15N whereas I keep getting 35N as I think that force at C is acting upwards and is acting anticlockwise and B and Q are both acting clockwise, can anyone tell me any rules I'm missing out here or mistakes I am blindly making?

5. I agree that the reaction at B is 60N. You then need to take moments about another point, but this time in the rod BC. Note that the reaction at B is still acting in BC.

Do moments about A to get the force at C, and do moments about C to get the force at A. Remember to include every force along the poles
7. Have you got horizontal and vertical components of the contact force at A. did you take moments about A?
