I basically have to solve the system below for which angle theta it's in balance. Meaning all forces equal out to 0. The answer is in terms of the variables. It's been a while since i've done statics like this but it has come back to bite me in the *** again. I started out by moments about A: 2L*cos(θ)*Cx - P*L*sin(θ) But now what? If I do sum of forces in X I get that Ax = Cx and then I get stuck with the sum of forces in Y Do I have to make a cut somewhere? Not sure about to go about solving with the spring. The answer is: cos(θ) = 0.5*(1+(P/2kL)) Any ideas?
