Answer:
The elevator has cable attached to it that goes up, around a pulley, then comes down and attaches to a counterweight. The motor that moves the elevator car uses much less power since the counterweight keeps the elevator balanced. ... By pulling on the rope, the pulley moves and the object raises.
Explanation:
Elevators, like all complex machines, are made up of several simple machines working together. Unseen by most elevator users are the hidden parts needed for an elevator to work. These include the metal box or “car” a user rides in, counterweights for balance, an electric motor and braking system, pulleys with cables that run between the motors, and a safety system in case a cable breaks. All of these key parts are made from six simple machines.
