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

please can you answer?  I can't do this.

Hello. I asked this question earlier but didn't get a good clear answer. I'm still a little confused. I can't find an equation for diffusion current density and I'm not sure how to work in the width into the equation.  Thank you for your time and help.

A support beam within an industrial building is subjected to vibrations along its length, which originate from two machines situated at opposite ends of the beam. The displacement caused by the vibrations can be modelled by the following equations: x₁ = 1 = 3.75sin (100nt) X2 = 5.17sin (150nt) i) When both machines are switched on, how many seconds does it take for each machine to produce its maximum displacement? t X1 X2 ii) At what time does each vibration first reach a displacement of 2 mm? iii) Derive a formula that shows when xy = x₂ = 0. iv) Use the compound angle formulae to expand x and x into the form Asin (100nt)+Bcos (100nt), where A and B are constant numbers to be found. 1 v) Using your answers from part (iv), express x₁ + x, in a similar form, and convert this expression into the equivalent form: R sin(100nt + a). vi) Using appropriate spreadsheet software, copy and complete the following table of values: 0.000 0.002 0.004 0.006 0.008 0.010 0.012 0.014 0.016 0.018 0.020…
