I've included a picture of the problem so you can see the diagram too. The question is asking for the tension of 1 cable, when 2 are given (problem# 41).
no equations per se.
The Attempt at a Solution
I resolved cable AC and cable AD, but don't know how to proceed. How do you even analyze it with the given info that "the resultant of the tensions exerted at point A of the boom must be directed along AB"? This is hard. Thanks for helping me.
