An electric train runs between two sub- stations 6 km apart maintained at voltages 600 V and 590 V respectively and draws a constant current of 300 A while in motion. The track resistance of go and return path is 0.04 Q/km. Calculate : (i) the point along the track where minimum potential occurs (ii) the current supplied by the two sub- stations when the train is at the point of minimum potential.

in Manila, the LRT runs between Gil Puyat Station and Tayuman Station, which is 4 km apart and maintains voltages 420 volts and 410 volts respectively. The resistance of go and return is 0.05 ohm per km. The train draws a constant current of 300 A while in motion. What are the currents supplied by the two stations if the train is at the distance of minimum potential?

A 0.1-W small cylindrical resistor mounted ona lower part of a vertical circuit board is 0.3 in long andhas a diameter of 0.2 in. The view of the resistor is largelyblocked by another circuit board facing it, and the heat transferthrough the connecting wires is negligible. The air is free to flow through the large parallel flow passages between theboards as a result of natural convection currents. If the airtemperature at the vicinity of the resistor is 120°F, determinethe approximate surface temperature of the resistor. Evaluateair properties at a film temperature of 170°F and 1 atm pressure.Is this a good assumption?

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
