The century-old ascensores in Valparaiso, Chile, are small cable cars that go up and down the steep hillsides. As (Figure 1) shows, one car ascends as the other descends. The cars use a two-cable arrangement to compensate for friction; one cable passing around a large pulley connects the cars, the second is pulled by a small motor. Suppose the mass of each car (with passengers) is 1700 kg, the coefficient of rolling friction is 0.030, and the cars move at constant speed. Figure 35° Motor Pulley 1 of 1

Question
Transcribed Image Text:The century-old ascensores in Valparaiso, Chile, are small cable cars that go up and down
the steep hillsides. As (Figure 1) shows, one car ascends as the other descends. The cars
use a two-cable arrangement to compensate for friction; one cable passing around a large
pulley connects the cars, the second is pulled by a small motor. Suppose the mass of each
car (with passengers) is 1700 kg, the coefficient of rolling friction is 0.030, and the cars
move at constant speed.
