1. The problem statement, all variables and given/known data The 60 lb collar "A" is on a friction-less vertical rod and is connect to a 65 lb counterweight "C". Determine the value "h" (which is the height between "A" and "B") for which the system is in equilibrium. Also, find the horizontal force "N" acting on collar "A". Here is a rough typed up picture of what the picture looks like, the zeros (0) are empty space <--15in--> 00000000B0 ^ 0000000/0|0 | 000000/00|0 | 00000/000|0 | 0000/000 C0 h 000/0000000 | 00/00000000 | 0/000000000 | A0000000000v The horizontal distance between A and B is 15 in. There is a pulley at B and a rope/string going from a A to B, and B to C. From what I can tell, the rope is continuous from points A to C. I have no idea where to get started on this or how to ultimately find h or the horizontal force acting on point A. A is a 60 lb weight. C is a 65 lb weight. 2. Relevant equations All I have so far are these few things: ∑Fx = 0 ∑Fy = 0 TBC = 65 lb TBA = 65 lb 3. The attempt at a solution I really don't know where to begin with this problem. I'm thoroughly confused as to how I should go about finding "h" or the horizontal force at "A", and I haven't been able to find similar problems to this one. If anyone can help me out, it'd be much appreciated.
