Homework Statement
The mayor of a city decides to fire some city employees because they will not remove the sag from cables that support the city traffic lights. If you were a lawyer and knew some physics, what defence would you give on behalf of the employees? Who do you think will win the case in court?
Homework Equations
The Attempt at a Solution
I'm thinking of the theory of Forces in equilibrium. Even if you remove the sag by increasing the tension in the cables, the light will always be motionless, but there's always the force of gravity pulling it down. Thus, the cables will still sag.
Does this make sense?
