(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The system is in equilibrium. What are the coordinates of point A?

(see attached image)

2. Relevant equations

ƩF_y = 0

ƩF_x = 0

3. The attempt at a solution

The sum of forces in the x and y directions is zero since the system is in equilibrium. At point A, I also know that there is a weight W directed downwards, and each of the two tensions in the ropes T are equal in magnitude.

I was told that this "proof" problem required consideration of the distance between the weight on the left and its pulley (call it ε), and also the two angles (α and β) between each of the two ropes at point A with the horizontal.

Although I was given these hints, I still can't figure out where to start in the problem. Can anyone help me out here? Thanks!
