4. How does an elevator move up and down?The elevator car is hung from steel ropes that go over a pulley. A motor turns the pulley, and a counterweight on the other side balances the car, so the motor only has to lift the difference in weight.
5. Why are elevators important for tall buildings?Elevators let people travel quickly between floors, so buildings can be very tall and still be useful. Without elevators, skyscrapers would be hard to use.

Traction Elevator: An elevator system that uses steel ropes and a pulley driven by a motor to move the car.
Hoistway: The vertical shaft or compartment through which an elevator car travels.
Machine-Room-Less (MRL) Elevator: An elevator design where the motor and controls are integrated within the hoistway, eliminating the need for a separate machine room.
