1. The problem statement, all variables and given/known data An 11 kg traffic light hangs fro ma structure as shown. The aluminium pole AB is 7.5 m long, and weighs 8 kg. Determine the tension in cord CD 2. Relevant equations T = rf 3. The attempt at a solution Ignore the AC height of 3.8 m, and replace it with an AD length of 7.5 m. Would the pivot point be A or D? If D, how would I find the r for D to B? For the equation ΣT = r1f1 + r2f2 + r3f3, with r1f1 being the pole, r2f2 being traffic light, what would the cale be as? I understand how to do the calculations, but looking at this I'm not entirely sure on how to get the F for the cable. I know that it'll be either sin or cos 37 to take into account the angle, but I'm lost.
