Civil engineers can use vibrations to study the behavior of structures without disturbing them. For example, it is possible to determine the tension in a bridge support cable by determining the frequencies with which it oscillates when the wind blows past. Consider a 3 m-long strand of 3/8- inch steel support cable for a bridge. A spool of 150 m of such cable has a mass of about 55 kg. If the cable has a fundamental frequency of 20 Hz, what is the tension in the cable? What would the frequency be when the cable reaches its design load limit of 12.8 kN?
