Nuts About Bolts
Every connection bolt gets exactly this many nuts
What is one?
This award celebrates the team’s colour, costumes, cheer, and overall identity.
What is theme?
Judges check bridge dimensions before loading, with this removable roadway material absent.
What is decking?
This award goes to the bridge with the lowest aggregate deflection.
What is stiffness?
One dropped bolt touches the river once during timed construction. This time penalty applies.
What is 15 seconds?
Parts of an individual member are joined using this fabrication process.
What is welding?
The live oral presentation has this target duration, before the separate judges’ question period.
What is 5 minutes?
These designated ground areas are where the bridge’s supports belong.
What are footings?
This horizontal force is applied during the lateral load test.
What is 50 pounds?
A builder steps into the river while building, rather than retrieving a dropped object. This penalty applies for each occurrence.
What is 2 minutes?
Measured from beneath the head to the end, a loose bolt cannot exceed this length.
What is 3 inches?
In 2027, construction speed combines total construction time with this other total time.
What is total deconstruction time?
Above the river and riverbank, the bridge must provide at least this much vertical clearance.
What is 1 foot?
To pass the lateral load test, sway must not exceed this amount.
What is ¾ inch?
Each connection identified for repair after construction adds this much to total construction time.
What is 1 minute?
This term describes a member’s surface that touches another member at a connection.
What is a faying surface?
This category rewards the lowest calculated deconstruction cost.
What is circular engineering?
Judges slide this device along the stringers to check their alignment and clearance.
What is the stringer template?
During vertical testing, loading stops if any measured downward deflection exceeds this amount.
What is 3 inches?
A team stages its bridge for construction but misses its scheduled aesthetics judging. This amount is added to its overall performance rating.
What is $1,000,000?
To fully engage a nut, the bolt’s terminal threads must reach at least this far.
What is flush with the nut’s outer face?
This category accounts for half of the final scoring.
What is overall performance?
A usability dimension exceeds its permitted limit by ½ inch. This much weight is added as a penalty.
What is 100 pounds?
D1 measures −0.24 inches and D2 measures +0.18 inches. This is the aggregate deflection. Hint: Math
What is 0.42 inches?
Construction takes 31 minutes. Before other applicable penalties, the spreadsheet records this construction time.
What is 180 minutes?
