Lessons 1: Moving On Up
Most elevators that move people and materials between floors operate by converting electrical energy into mechanical energy. These types of lifts are called traction elevators. They make use of a heavy counter-weight to offset the weight of the elevator cab, people, and objects.
Doing the science
- Start the Energy Downer Simulation by clicking on the "Sim" tab.
- Click on the "Traction" icon under Elevator Type.
- Note and record all of the relevant information about the elevator in Table 1.
- Click on the "Maximum Load" button located at the bottom of the screen. Note and record the new Elevator Load in Table 2.
- Click the "Up" arrow on the elevator. Note and record the "Motor Energy" in Table 2.
- Click the "Down" arrow on the elevator. Note and record the "Elevator Load" and "Motor Energy" in Table 2. Repeat this process until all people are moved up and the Time of Day changes to evening.
- Repeat the investigation to collect data for moving the people in the evening from the upper floors back down to the first floor. Note and record this information in Table 2.
