$100

Second Prize

Second most efficient bridge

$60

Third Prize

Pick up your FREE supplies at the STEM Centre Office, room E-302 (as of October 9th). Registration closes at 4:00p.m. on Monday, October 30th, 2017.


Completion Date

Judging of the bridges will take place on Wednesday, November 16th at 12:30 p.m. in Jake's Mall. Bridges must be delivered, in a protective box, to the Marketplace between 10:00 a.m and 12:00 p.m. on the morning of the same day.

What materials can be used?

The only materials allowed are provided FREE by the STEM Centre and will be available for pick-up as of October 9th.

- 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 or stained.

What are the physical specifications of the bridge?

  • Mass

    The total mass of the completed bridge MUST NOT exceed 225 grams at weigh-in. (A scale is available for use in B205-E).
  • 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 in height.

    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. i.e the official model car, approximately 7cm x 2.5cm x 2.5cm must be able to drive, smoothly and without obstruction, from one supporting surface to another. 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 impractical.

    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 judging occur?

- The contest organizers will ensure that the bridges submitted conform to the contest rules prior to the competition. Please bring your completed bridges to E-302 for inspection by Monday, November 6th.

- A loading device will be provided to contestants at the competition. 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 above. Please ask to view an example in E-302.

- 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 the load.
