Hint L10 - Gears

Some K'NEX sets come with K'NEX gears. They can also be bought separately as parts in our Technology 2 enjoy website.

The gears enable a turning motion in one K'NEX rod to be transferred so as to become a turning motion in a second, parallel K'NEX rod.		Hint L10 - Gears
L10d Some K'NEX gear wheels have teeth that extend beyond the surface of the wheel. These are known as "crown gears". This allows the gear wheel to also transfer a turning motion from one K'NEX rod to another K'NEX rod at right angles to it.
The red and yellow gears in the photos above are the same width, 55mm.

A much larger crown gear is also available, 130mm in diameter, as shown in the photo opposite.		L10e
L10b If you do not have any K'NEX gear wheels, a gear wheel may be made by putting 8 green rods into the 8 slots on a white connector. Two such wheels may then be used in combination, either to transfer motion between two parallel rods, or between two rods at right angles to each other.
