Simple Machines Series: Rack and pinion gear (linear)

MACHINE TRANSLATION (not authorised yet)

The rack and pinion gear is one of 12 running experimental models of our series of simple machines. Like all simple machines, you can use it to show the gain on force, calculate it and find practical application. Examples of a reel are, after all, bicycle wheels, windmills, handlebars...

This experimental model is accompanied by an instruction with theoretical discussion and ready-made work sheets for teacher and student (separate!):

1. The steering wheel.
2. Bike gearbox.

All simple machines of this series are made of friendly material - wood. Dimensions: 40x6x15 cm. Weight 550g.

This teaching aid seems so simple? That's good! Because this is a MACHINE MODEL PROFECT!

The simple machines can be seen everywhere around us, even in very complex devices. We can even find them in ourselves... Just pull out your arm and bend it in your elbow.
Experiment with our simple machines - we attach detailed work sheets for teacher and student.
Present serious patterns in practice! Only such learning makes sense.

The series of simple machines includes 12 models of simple machines - 6 basic and 6 complex machines designed for practical experience of their operation, illustrating the profit on power achieved by using a given machine, but also for calculating this profit based on specific machine settings in the form of our model.
