Electrical transmission towers are stationed at 350 m intervals and a conducting cable 2cm in diameter is strung between them. How many wires should each tower carry toensure structural integrity during a tropical storm? The towers are designed to withstandup to 180 kN of transverse force and during a cyclone, wind can blow up to 200 km/h.Assume there is no interference between the wires and take air density as 1.2 kg/m3and viscosity as 1.7×10-5 Nsm-2 . If the smooth insulation on the wires is mechanicallyroughened up before application what effect it will have on the design? Also, establishwhether the wires are likely to be subjected to self-induced vibrations and if so what the frequency would be. The frequency of such forced vibration, sometimes called self-induced vibration, may be calculated from an empirical formula due to Vincent Strouhal: fd⁄Uo = 0.198(1 − 19.7⁄Re) 250 < Re < 105
