## Homework Statement

http://members.shaw.ca/code/2.133.JPG

Two Cables tied together at C are loaded as shown. Determine the range of values of Q for which the tension will not exceed 270N in either cable. Solve graphically and Numerically.

## Homework Equations

law of cos, law of sine

sum of Fx = 0

sum Fy = 0

## The Attempt at a Solution

I'm really not sure where to start with this one, probably because I don't fully understand the question. I am assuming that I should set AC = 270N and BC= 270 N. And then find all components such that sum of Fx = 0 and Sum Fy = 0. This will be the Max vaule and the resultant of BC and AC plus P should give me Q? I am getting an answer like this, but it's not making sense.
