The Elevator Counterweight

A hidden weight means the motor barely lifts anything

An elevator full of people can weigh as much as a pickup truck. How does a modest motor haul it up dozens of floors?

You'll find out

  • What hides in the shaft beside the car
  • Why the motor barely works
  • How an elevator can make electricity

Why it matters

It's a trick you ride every week, and it's why tall buildings don't need giant motors.
