A 7.5kg sign is hung off of the end of a 3.7kg metal arm as shown in the figure. (Note that while the arm is made from one material, it is tapered such that the arm’s center of mass is 1.5m from the bottom end.) The arm is allowed to pivot about a bolt that connects the arm to the building. What is the tension in the cable which connects the arm to the building?
