The Elements of Machines

Simple Machines:
These devices were all in common use for centuries before Leonardo's time. Each one makes work easier to do by providing some trade-off between the force applied and the distance over which the force is applied.

Other Elements of Machines:
Though these devices were also used in machines in Leonardo's time, he experimented with them and made changes to improve how they worked. He also combined them in many exciting new ways to create machines and inventions that had never been seen before.



Now that you have seen the various elements of machines, you can try to figure out which ones are used in some common devices by going to the Gadget Anatomy page.
