Simple Machines Series: Crank mechanism

MACHINE TRANSLATION (not authorised yet)

The crank mechanism (reel change - change of the rotational movement into a reciprocating movement) is one of the 12 operating experimental models of our series of simple machines. Like all simple machines, you can use it to show the profit on force, calculate it and find practical application. Examples of a reel are, after all, steam engines (steam engine), car engine pistons...

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

1. Practical.
2. Principles of operation.

All simple machines in this series are made of friendly material - wood. Dimensions: 39x7x15 cm. Weight 1kg.

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.
