Question

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 1400 kgkg, the coefficient of rolling friction is 0.030, and the cars move at constant speed.

Figure

1 of 1The figure shows two cable cars at a 35 degrees incline. A lower car is connected to a cable, which is fed through a pulley uphill. From the pulley the cable runs to the second car down the hill. From the second car another cable runs uphill to a motor. The lower car moves downhill while the upper car moves uphill.

Part A

What is the tension in the connecting cable?
