Purposes of the Elevator

• Transports people or objects to different levels
  of a building
• Hospitals can install elevators, and emergency
  room patients can get to the emergency room
  quickly
• Takes up less room than stairs and elevators
• Allows handicapped people to travel from floor to
  floor in a building with ease
• Buildings can be taller and thinner because, they
  can have enough room with many floors leaving
  room for other buildings to be constructed

Influence on Other Inventions

• The elevator makes it possible for cities to
  be made up of
• skyscrapers. Walking up stairs is more of a
  hassle than
• riding in an elevator if you are going to the
  top floor of a
• tall building. In 1850, steam and hydraulic
  elevators were introduced, and shortly after the
  Era of the Skyscraper took place. The escalator
  was inspired by the elevator and was invented
  later.

• Yes, anybody can ride in an elevator, and it is
  so easy to use, that almost anyone can control
  where it goes. All that a person has to do is
  press the button of which floor they want to go
  to, and it will take them to their destination.
• Does this invention eliminate risks?
• Elevators can get stuck while in use, but most
  have an emergency button or telephone in them, so
  if a person gets stuck in an elevator they can
  call somebody to get them out. It is better to
  use stairs if there is a fire in the building.
