The hinge
joints facilitate the inherent instability of the structure. You can |
|
attach parts of the model you want to be moveable to the plates
surrounding |
|
the pistons. The parts will then move with a hinging or back and forth |
|
movement
as the pistons move in and out. Such redirection of movement |
|
is an essential feature of
many mechanisms. It allows one type of motion |
|
to be converted into
another, more useful form. For example in gasoline |
|
engines the up and down
movement of the pistons is converted into the |
|
rotation of the drive
shaft by the connecting rods and crankshaft. |

You can
make the pistons reciprocate |
|
directly
by hand. |
