Thank you for all of your help, but I only just now discovered that the professor changed the problem to include the vertical distance the rope sags after loading and reaching equilibrium. I should be able to figure it out from here. Thanks again! :)

Each of those stated equations require knowing the change in length to calculate the force.

The way I still see it, I still don't have: the force for the F/A = tensile stress, the final length of the rope, and the change in length of the rope. Am I missing something here, or is there some other method we should be going about this?

"w.r.t."?

So then what do you do with those 2 unknowns?

The change in the length of the material = ((tensile stress)/(young's modulus))(final length of the material). But the stress = force/area and since I'm not given the force or the angles or enough other geometric values, how can I solve for this?

In the book, it is given as 5x109 N/M2. But this problem is not out of the book, so it's a bit of a stretch.

Homework Statement I am confused on how to begin finding the angles (theta) for answering part a?
