I need to find the angle that the two rods will have the same stress. We are talking about normal stress here!
[itex]\sigma[/itex] = Force / Area
The Attempt at a Solution
I am using the method of joints to solve for the internal force because they are both two force members. I have the equations for x, and y.
-AB + BC cos(θ) = 0
-50 + BC sin(θ) = 0
Where do I go from here? I want to start solving in terms of something to be able to put them into the stress formula.
