(adsbygoogle = window.adsbygoogle || []).push({}); A ring of negligible size is subjected to vertical force P. Determine the required lengthlof the cord AC such that tension acting in AC is TAC. Also, what is the force acting in cord AB?

P = 300N, d = 0.2m (distance between A & B), angle ABC = 45 degrees, TAC = 250N

The graph basically looks like a "Y" with C & B at the tops, A at the centre and P the downward force.

Fx = 0; Fab(cos45) - 250cosx = 0

Fy = 0; Fab(sin45) + 250sinx - 300 = 0

Fab = (250cosx/cos45)

(250cosx/cos45)sin45 + 250sinx - 300 = 0

This is about as far as I get before I start mucking it up. Can some one help me through the steps to solve for "x" so I can eventually findl?
