Simple Machine Shipyard

A simple machine is a mechanical device that makes work easier.

Simple Machines use mechanical advantage (also called leverage) to multiply force. Usually the term refers to the six classical simple machines which were defined by Renaissance scientists: Wedge, Lever, Screw, Pulley, Wheel and Axle, and Inclined Plane. They are the elementary “building blocks” of which all complicated machines are built. And you can put them to work at Discovery World!


  • Wedge: A wedge is a triangular shaped simple machine that is used to separate objects or portions of an object.
  • Lever: A lever is a simple machine that uses a long rod or bar to multiply the applied forces on an object.
  • Screw:A Screw is a cylinder with spiral ribs or ridges called threads.
  • Pulley: Used to change the direction of a force or to apply a mechanical advantage, a pulley consists of a cylindrical drum and a cord commonly made of rope. You can use ours to hoist your parents or a friend!
  • Wheel and Axle: A wheel and axle act like a lever that rotates in a circle around a center point.
  • Inclined Plane: An inclined plane is a slanted surface that connects two points of alternate elevation.
