yes this is what i meant to say :D
So when an object is in equilibrium,the frictional force will take a value equal to the horizontal force ;)

Bingo :P

I know that the tension is the same all round the system, but I don't know which directions each one are (could someone draw the arrows to show them, thanks!)
My (wrong) answers:
a) For equlibrium to be achieved, forces are balanced, zero resultant.
b) i) 141N
ii) 131N
iii) No idea! Difference is not 0N, I'm stuck!
Many thanks in advance!

Understood you perfectly br0 ;)
I had the same thinking in mind but i think i misplaced my words. When I said frictional force is greater than the tension, I was referring to the maximum constant value that the friction may reach ;)
By the way good job :D
