    Ya can't figure anything on this problem? Ya can't at least calculate the components of vector A?

    The ring is at rest. What does this tell you about the sum of all of the forces acting on it?

    Attempted the question. Attached is my working. Does it make sense?

    You double quoted my post. Do you have anything else to add?

    Well, now you're double posting blurry images, but it looks like you have decomposed vector A into its components.

    NOTE: Your last image post came out sharp and clear. :smile:

    Do you understand how the components of A must match up with vectors B and C to put the ring in equilibrium?

    Sorry for the blurry images and the double postings.

    Haha..

    Actually, I may need help with the reasoning. Hehe

    Next time you attempt these questions, remember when a body is at rest, you can equate vertical and horizontal components of force to work out tension or whatever quantity you are trying to find.
