An elevator car, with a mass of 450 kg is suspended by a single cable. At time = 0s, the elevator car is raised upward. The tens
ion on the cable is constant at 5000N during the first 3 seconds of operation. Determine the magnitude of the velocity of the elevator at time = 3 seconds.
The turns ratio is equal to the voltage ratio. Let n1 and n2 be the primary and secondary turns. Then 5850V/120V=n1/n2 48.75=2680/n2 n2=2680/48.75 n2=55
