Simple Machines Series: Screw

MACHINE TRANSLATION (not authorised yet)

The screw is one of 12 running 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 screw application are, after all, jar caps, drills, meat grinders, corkscrews and, of course, screws...

With this experimental model there is an instruction with theoretical discussion and ready-made work sheets for teacher and student (separate!):

1. How much profit on strength?
2. Practical use of profit on strength.

All simple machines of this series are made of friendly material - wood. Dimensions: 19x10x11 cm. Weight 680g.

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.
