You are an employee of the city of chicago. a city official declares that all cables holding traffic lights in the city should be exactly horizontal and asks you to direct the project. what should be your reply? a. that's impossible, because according to newton's second law, there must be an upward component of the tension in the cable that balances the weight of the traffic light, and therefore, the cable can never be exactly horizontal. b. no problem. all we have to do is increase the horizontal tension in the cable. c. no problem. all it takes is a pay raise. d. that's impossible, because by newton's third law, the cable pulls horizontally on the poles with a force of the same magnitude force as the force with which the poles pull on the cable. therefore, if the horizontal component of the tension is too large, it will pull the poles inward toward the cables.

Astudent weighing 160 pounds hangs for dear life from a cable tied to two other cables fastened to a support as shown above. the upper cables make angles of 39º and 55º with the horizontal. these upper cables are not as strong as the vertical cable and will break if the tension in them exceeds 500 n.
