The Learning Center, Student Services, Vanier College, Room B205,
Objective: To build a practical
bridge that allows vehicles to pass from one side to the other.
WILL BE TESTED FOR THE GREATEST LOAD, BUT THE WINNING
ENTRY WILL HAVE THE GREATEST EFFICIENCY FACTOR (LOAD/ MASS RATIO)
First prize -most efficient bridge -$125.00
Second prize -second most efficient bridge -$75.00
Third prize -third most efficient bridge -$35.00
Fourth prize -bridge holding the greatest load -$25.00
Prize will also
be awarded for craftsmanship and aesthetics.
Please note that all decisions are final.
Who can enter?
Any individual or team of individuals can enter. We recommend
teams of two to four people. Vanier College or high school students
are eligible to participate.
All contests must register at The Learning Centre , Room B205,
before 4:00p.m. on Friday, November 8, 2002
Judging of the bridges will take place on November 13 at 12:00
p.m. in the Quiet Cafeteria (N131), N Building. Bridges must
be delivered, in a protective box, to the Quiet Cafeteria (N131)
before 10:00 a.m. on the morning of the same day.
can be used?
The only materials allowed are provided FREE by The Learning
- one package of spaghetti noodles
- one bottle of white carpenter's glue
The construction must not contain any other materials than those
specified by the contest rules. The noodles may be cut, carved,
notched, steamed, boiled and curved. The bridge must not be painted
What are the
physical specifications of the bridge?
A. Mass: The total mass of the
completed bridge MUST NOT exceed 225 grams at weigh-in.
B. Size: Length: The gap to be spanned is 40.0 centimeters
(+/- 0.4cm). The bridge must be at least 43 centimeters and no
more than 45 centimeters long. Width: The bridge must be at least
4.5 centimeters wide and no more than 7.0 centimeters at its
widest point.Height: The bridge should not exceed 25.0 centimeters
Road: The bridge is meant
to be practical. It must include a roadbed that provides a CONTINUOUS
UNOBSTRUCTED passage from the supporting surface on one side
to the supporting surface on the other. The official Learning
Centre model car, approximately 7 cm X 2.5 cm X 2.5 cm, will
be passed from one side to the other and must be able to pass
smoothly and without obstruction. The roadbed can pass on or
through the bridge, but if the car cannot pass, having encountered
an obstruction or having fallen through, it will be considered
The roadbed must
have an opening of at least 1 cm in diameter through the centre
of the bridge which allows the judges to insert a loading device.
How will the
- The contest
organizers will ensure that the bridges submitted conform to
the contest rules prior to the competition on November 13 at
TO BRIDGE BUILDING 2002 MAIN PAGE
- A loading device will be provided to contestants when they
register and collect their glue and noodles. The loading device
is 3.5 cm by 3.5 cm by 10 cm and has a 1 cm hole which must be
aligned with the hole in the bridge must allow the judges to
insert the hook from below and fasten a threaded wingnut from
- The hook will be fitted with a load which will be gradually
increased until bridge failure occurs.
The following are the conditions which represent bridge failure:
a) The bridge collapses and falls with the load;
b) The bridge does not collapse or break but bends (deflects)
5 centimeters or more;
c) The bridge breaks in such a way that it no longer supports
