2016-02-27 11:09 Does the "0.9 m in any dimension" limit go beyond width, depth and height to include all possible diagonal dimensions?

No, "0.9 m in any dimension" refers only to width, depth, and height.

2016-03-29 11:19 Is it OK for competitors to bring multiple different weight falling masses to choose from, as long as none of them weigh more than 2.00kg.

No, throughout the rules the mass is referred to as singular. Teams may impound only one mass.

2016-03-29 21:02 Is it legal to use lead as part of the weight? We intend to use lead, but we are concerned about it being a hazmat. We intend to keep it completely wrapped in duct tape so that the lead is not exposed, but is it legal?

Please do not use lead. First because it is not a safe material to be working with and second, simply because many, many Event Supervisor just would not allow it. There are a number of safer materials available out there that are close to the density of lead.

2016-03-29 20:59 My egg backstop is completely rigid but it is attached to a ETV that has a flexible chassis. Is that allowed?

No. Rigid is defined as "stiff", "hard", "unable to bend or be forced out of shape; not flexible". A flexible chassis is able to bend and therefore can easily absorb the energy of pressure from the egg hitting the wall. The whole purpose of a rigid backstop is to ensure that if the egg hits the terminal barrier with enough force it will break. The purpose of the entire event is to see how close you can get to the wall as fast as possible without breaking the egg. The purpose is not to see how we can circumvent breaking the egg by using essentially a "crumple zone," which is exactly what would happen with a backstop attached to a flexible chassis. The term "rigid" goes beyond just the backstop. You can't maintain rigidity if you attach something that is rigid to something that is not rigid. See rule 2.e.line 6

2016-03-29 10:48 This line calls for ...rigid material... to be used. If it meets all other construction parameters, can balsa be used as the rigid material?

Generally, no. Rigid is defined as "stiff", "hard", "unable to bend or be forced out of shape; not flexible". A block of balsa tends to be less dense and can easily absorb the energy of pressure from the egg. Please have an alternative backstop prepared in case your local tournament event supervisor does not consider balsa as a rigid material. This would have to be replaced during the team's 8 minutes.

2016-03-29 21:06 Do the wheels of the ETV have to be in contact with the floor in launch configuration? Or can they rest on a thin (not raised) piece of plywood?

Yes, all of the wheels have to be in contact with the floor in the ready to run position. No, they cannot rest on a (thin or thick) piece of plywood. If they were not on the floor in the ready-to-run configuration, they would violate Rule 2.h. upon touching the floor during the run and the team would receive a construction violation.

2016-03-29 11:33 Must the part of the Scrambler which is to prevent the falling mass from damaging the floor be structurally built into the Scrambler or may it be a separate added piece placed within the device as long as it fits in the size parameters?

It may be a separate piece but when placed within the Scrambler it must fit in the 0.90 size parameter.

2016-03-29 21:15 If the contestants break their egg while attaching to the vehicle, or before the first official run, do they get another egg?

A second egg will be provided, the team will be allowed only one run, and a competition violation will be assessed to that run even if the second egg does not break.

(section: 4 / paragraph: k / sub-paragraph: 3 / line: 3)

2016-03-29 11:47 If the egg breaks on the second run, and the first run has no violations, then the first run is in tier one and the second run is in tier 2 correct?

There are no Tiers in Scrambler this year. The runs are scored separately. The better of the two Run Scores is used for the Final Score.
