Wheels in an egg beater - Hand drill ..
The machines we use every day and how they work

Wheels in an egg beater:

The wheels in an egg beater perform a special task aimed at speeding up the processes of stirring and beating. To understand the means by which this work is performed, sharpen a small pencil from both ends 6 then hold the pencil between your index finger and thumb at its ends, then hold a large piece of money in your other hand. Spin the coin, then notice how slowly the pencil moves. You will find that every time you turn the coin once, the pen makes several revolutions.

The coin and the pencil are both wheels, but the circumference of the coin is larger than the circumference of the pencil

The pencil.

When a large wheel turns another smaller wheel, the speed increases. This means that the small wheel makes several revolutions while the large wheel makes one revolution.

The same idea (the idea of ​​wheels) is used in an egg beater. Your hand turns a large wheel, which in turn turns two smaller wheels. (We need these two wheels because there are two weapons that should be pushed in a circular motion).

These two small wheels make several revolutions each time, compared to one revolution made by the big wheel, and in this way you see that when your hand turns the big wheel one slow revolution, this revolution is the reason for the two weapons to rotate at a faster speed.

Hand drill:

The system that helps the egg beater to work quickly, (i.e. a big wheel turns smaller wheels), is the same system used in the hand drill. In this case - also - you turn the big wheel 7 one revolution, thus causing the small wheel to rotate many revolutions.

The tooth of this hand drill is connected to the small wheel and rotates with it.
