| Machines are complex structures built from moving and nonmoving parts for | ||||
| the purpose of performing some kind of function or work. Therefore they have | ||||
| elements of stability and instability which must be balanced. They have to be | ||||
| durable enough to withstand the loads imposed on them without structural | ||||
| failure. Yet they must be pliable enough to move in the manner required to | ||||
| perform their task. The following section shows how you can engineer simple | ||||
| mechanisms, or gizmos, utilizing the same geometric principles and properties | ||||
| illustrated in the prior lessons on polyhredra, crystal structure, and structural | ||||
| engineering. | ||||
| . | ||||
|
Gizmos are gadgets you can build with Polymorf to make your models come |
. | |||
|
alive! You can use these simple mechanisms alone or combined with each |
. | |||
|
other to make models of flying eagles, creeping spiders, pouncing cats, or |
. | |||
|
telescopes that have two-axis rotation. As a toy inventor you will learn how |
. | |||
|
to engineer complex mechanisms that use bearings, levers, pivots, push rods, |
. | |||
| hinges, braces, etc. to power the action that you desire. Polymorf is the toy | ||||
|
making toy! |
