Answer to Question #22937 in Abstract Algebra for vicktor

Question

I'm trying to rearrange the equation below to solve for the value of I. But I can't get it out of the second factor:

T = (W*L / 2*I) * (L-squared * I-squared * H-squared - 2 * I * H) quantity square rooted

(Sorry for the weird way of spelling it out. This !@#$%^&* yahooty won't let me use math symbols...)

I'm trying to solve for I in this tower guy tensioning formula thet uses the visual guy sag calculating method. The value of I represents the intercept distance below the guy attachment point on the tower and a visually observed point on the tower with a transit connected to the guy cable at the anchor to establish the guy starting angle and amount of sag resulting after tensioning, The guying distance to the tower, L, the height of the guy connection point, H, and the length and weight of the cable, contained in W, are known. T is the tension.
