regularly.
Event Description:
Teams of two to
three students construct a barge from the materials provided before the contest.
Points toward the final score are awarded for a quiz and for the maximal amount
of weight the barge can carry before it sinks. Both the building and the loading
of the boat have to be performed within a specified time limit determined by the
judges.
Event Location and Time:
Randall Building,
Rooms 1221 and 1233 |
Time:
10:30 - 11:50 a.m.
and
1:00 p.m. – 2:50 p.m. |
Apparatus and Materials:
Each team will be provided the following
material before the event.
- 2 sheet of standard copy paper, 11"
by 8˝" (Letter Size)
- 12 standard 1" paperclips
- one crayon
Only the materials provided are allowed
in construction of the barge.
Event Rules:
Teams: Each
team shall have no less than two and no more than three members.
Quiz: Prior
to the start of the competition each team will take a written quiz worth 30%
of the total score. The time allotted for the quiz is
10 minutes.
Building: Only
the materials provided before the event are permissible in building the
barge. One of the sheets of copy paper should form the hull of the vessel,
while the other one may be cut up to form stabilizing elements.
Loading: Only
one washer at a time may be added to the barge once it has been put into
the water tank. However, the barge may be preloaded before launch. Mind:
if the barge sinks immediately due to too heavy preload, no points will be
awarded!
There is a mandatory waiting period of 5 seconds between adding washers to
the barge (compare “Sinking” below). The total loading time, defined as the
time from placing the barge in the water to time-out, is 3 minutes.
Ballast: The
ballast are standard 2" washers; each washer loaded before sinking is
awarded one point.
Sinking: A
barge is considered sunk if it (a) starts taking water and starts to sink
within 5 seconds after a ballast weight is added (sunk by too heavy load),
(b) starts to take on water continuously through a leak (sunk by leaking),
or (c) when it loses any of its freight (sunk by capsizing).
Timeout: at
the end of the contest, when timeout is declared, no more weight may be
added to the barges and the total weight of those barges still floating will
be tallied.
If the barge is still afloat (i.e. judged to be not sunk) at the time
of time-out, a 5 point bonus will be awarded to the team.
Judging Criteria:
Total Score: The
total score will be determined as follows:
Total Score = (Quiz score x 0.30) +
(Number of ballast washers + time-out bonus) x 0.70.
Ties:
In the event of a tie, the team whose barge was still afloat at timeout shall be
declared the winner. Should a tie still exist, the team with the higher quiz
score shall be declared winner. If one or more teams are still tied after this,
they shall share first place.
Gold, silver and bronze medals will be awarded to the teams with the highest
three scores, respectively.
