A traffic signal weighs 150 N and hangs above an intersection. It is supported equally by wires on either side that form an angle of 120.0° with each other. (a) What is the tension in each of these wires? (b) If the angle between the wires is increased to 140.0°, what is the new tension? (c) Now suppose the left wire is tilted 20.0° from horizontal and the right is tilted 30.0° from horizontal. Again determine the tension in each wire.
