| Objective |
The objective of this contest is to construct a self-contained
device powered continuously and only by a 9 volt battery. The
device will propel the battery up an inclined length (12 metres)
of piano wire (#28) stretched across the room. The wire will be
set at a 3 degree incline.
|
| Purpose |
To develop skills in electric circuits
and motors. |
| Participants |
Teams of up to four people. |
| Materials |
The battery employed must be one standard
9 volt alkaline battery of a make to be determined by the organizers.
No substitutes accepted. Other materials are decided by the team. |
| Rules |
- The self-contained device carrying the battery may be propelled
up the wire by any mechanism which receives its power continuously
from the 9 volt battery. The battery must be the only source
of power.
- Each entry shall carry a 3 cm x 3 cm square of stiff paper
to be positioned with one of its sides 1 cm above and parallel
to the wire. This card will act to break a light beam which
will trigger the timing device.
- Each entry may make two runs. The better of the two times
will be used.
|
| Judging |
Recorded times will be ranked from shortest
to longest.
