Bungee Drop

(section: 3 / paragraph: b / line: 1)

2014-11-25 19:52 What is the definition of "drop height?"is it the bottom of the plastic bottle? The top? the top including all attached pieces by the event supervisors?The height of the anchoring system's top of ledge?

The drop height is measured from the bottom of the bottle.

2014-10-21 20:08 The phrasing for the sentence beginning "An attachment mechanism... " has very confusing wording. What exactly is it saying about attachment mechanisms (could you reword it for us?)

Rule 2.b.line 3 The phrase should be a complete sentence starting with the wording "Supervisors will supply an attachment mechanism......."

2014-11-25 19:58 Would folding the cord in half or other fractions/multiples to adjust for drop heights considered a physical alteration?

Folding the cord would not be considered a physical alteration. However, when folded, the cord would need to meet the elasticity test. Rule 3.c states "The cord may consist of more than one material...and more than one strand as long as it meets the elasticity test." Rule 3.c also defines the elasticity test "...while being suspended vertically, the bottom meter of the cord must stretch to at least 1.25 meters when a single mass is attached to this section and return to within 5 cm of its original length after the mass is removed."

2014-11-25 19:59 Does the bottom one meter length include the key ring for the elasticity test? i.e. the one meter length measured from the bottom of the key ring.

The key ring is included in the meter for the elasticity test.

2014-11-25 20:05 While writing can words be crossed off or erased if a mistake is made?

Yes, strikethroughs may be used to identify text that is not part of the completed instructions. Even though technically not acceptable since it cannot be made on a standard typewriter, students are not expected to perfectly write instructions and if mistakes are made, strikethroughs would identify that the text is NOT part of the written instructions ...therefore wouldn't be docked in scoring.
