1. A traffic light weighing 122 N hangs from a cable tied to two other cables fastened to a support as in the figure shown. The upper cables make angles of 37.0° and 53.0° with the horizontal. These upper cables are not as strong as the vertical cable and will break if the tension in them exceeds 100 N. Does the traffic light remain hanging in this situation, or will one of the cables break? TIY 53.0 37.0 53.0 (a) (b) (c)
