I am just seeing if i am on the right path. A simple yes or no would be enough.
Thank you
 
No, it's not quite right. Hint: What's the tension in the rope? Then you can sum the forces on the sliding collar.
 
Thanks Doc Al
I will look at it again when i get home from work.
 
I was going about this the wrong way, making it too complicated.
1st what I did was get the angle where the rope attached to collar A and the rod, γ = cos-1 (40/50), γ=36.87 ; the to find x I just used tan36.87= 20/x  x = 20/tan36.87 so the result is x = 26.67in.
I find that I over think a problem too much but I guess that is because I find it hard to find a starting point.

Thanks
