Textbook Question
Chapter 6, Problem 87P
The world’s fastest elevator, in Taiwan’s Taipei 101 skyscraper (Fig. 6.18), ascends at the rate of 1010 m/min. Counterweights balance the weight of the elevator ear, so the motor doesn’t have to lift the car’s weight. If the motor produces 330 kW of power, what’s the maximum number of 67-kg people the elevator can accommodate? (Your answer somewhat overestimates the actual rated load of 24 people.)
