(section: 3 / paragraph: e / line: 1)
No. A wheel and axle (as a simple machine) requires an input on the wheel or axle and an output on the other end (axle or wheel). A toy car rolling down a ramp does not satisfy the requirements of transferring from one simple machine to another (see rule 3.d).
Each simple machine must complete the requirement listed in the rules before the next machine's requirements start to be counted. If this does not happen only one of the simple machines will count for a score as long as it completes its listed requirement.
(section: 3 / paragraph: h / line: 1)
Parallel tasks have no direct relationship to one another and if one of the two tasks fails, the overall sequence of events can still continue or lead to a “dead-end” path. Parallel tasks are not measured in a chronological manner but in a causality manner. That is to say, if one task causes the next task, then they are not parallel. A Dead End Path does not lead to the Final Task.
(section: 3 / paragraph: J / line: J)
No, there does not need to be a non-scorable simple machine between two scorable transfers. Scorable transfers are based upon the first simple machine in a transfer. The second simple machine of the first transfer can then become the scored first simple machine of the next transfer.
(section: 4 / paragraph: c / line: 1)
Yes, there can be a release of stored energy between the two simple machines in a transfer. No, the output of the first simple machine does not have to directly drive the input of next one.
No, you can not have a scorable transfer from one Class Lever to a different Class of Lever. They are classified as the same type of Simple Machine, just different classes. See rule 4.c.
(section: 4 / paragraph: d / sub-paragraph: iii / line: 1)
Yes, an object must travel upward at least 10 cm along the surface of an inclined plane. The 10 cm minimum required distance is not the vertical distance between the lower starting point of the object and the higher point where the object ended.
(section: 4 / paragraph: d / sub-paragraph: iv / line: 1)
No, this will not qualify as a wedge separating two touching objects.
(section: 4 / paragraph: d / sub-paragraph: IV / line: 1)
A wedge as a simple machine functions by converting a force applied to its blunt end into forces perpendicular (normal) to its inclined surfaces.
(section: 4 / paragraph: d / sub-paragraph: v / line: 1)
According to rule 4.d.v., the "screw must complete at least one full rotation..." An object moving around the threads of a stationary screw will not satisfy this requirement.
(section: 4 / paragraph: d / sub-paragraph: vi / line: 1)
The simple machine of a Wheel and Axle is a larger wheel fixed to a smaller axle and a mechanical advantage is gained by the ratio of the difference in their diameters. So if the wheel turns 360 degrees and the axle does not turn 360 degrees, it is not a wheel and axle simple machine because they are not fixed together.
(section: 4 / paragraph: j / line: 1)
Yes, the student may ring the bell. They will incur a 15 point penalty for a touch and they will not receive the final task points. rule 4.l. Any obvious stalling to gain a time advantage must result in disqualification. Rule 4.j.
(section: 5 / paragraph: h / line: 1)
The completed Start Task - "dropping an unaltered, regulation-sized racquetball into the device to initiate the first action" can not be listed as the first scoreable transfer. The first action (simple machine) initiated by the Start Task may be the initial type of machine in the first scoreable transfer (rule 4.c.1.) and must be listed on a separate line on the TSL. See posted TSL sample on the National website.
(section: 2 / paragraph: a / line: 3)
No, "0.9 m in any dimension" refers only to width, depth, and height.
(section: 2 / paragraph: c / line: 1)
No, throughout the rules the mass is referred to as singular. Teams may impound only one mass.
(section: 2 / paragraph: c / sub-paragraph: N/A / line: 1)
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.
(section: 2 / paragraph: e / line: 2)
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
(section: 2 / paragraph: e / line: 5)
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.
(section: 2 / paragraph: h / line: 1)
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.
(section: 2 / paragraph: i / line: 2,3)
It may be a separate piece but when placed within the Scrambler it must fit in the 0.90 size parameter.
(section: 4 / paragraph: j / line: 2)
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)
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.
(section: 3 / paragraph: a / line: 2)
Per rule 5.b.ii. Teams may place the Test Support in one of the Bearing Zones, it does not need to be exactly on the 35 cm line.
(section: 3 / paragraph: e / sub-paragraph: N/A / line: N/A)
The loading block is to be aligned with the centerline of the test base which would be the center of the Bridge span when it is placed on the Test Support on one side and the Bearing Zone of the Test Base on the other side.
(section: 3 / paragraph: f / line: 1)
Yes, this is allowed.
(section: 4 / paragraph: c / sub-paragraph: i / line: 1)
No, the 2 cm x 5 cm x 5 cm block will not be secured to the Test Base.
(section: 5 / paragraph: b / sub-paragraph: i / line: 1)
If the test support falls over, loading will stop and the weight held at that time will be used to calculate the final score. There will not be a second try at testing the bridge.
(section: 3 / paragraph: b / line: 3)
No, rubber bands are specifically not allowed to attach the wing or stabilizer to the fuselage for safety. The wing or stabilizer could become separated from the fuselage during launch.
(section: 4 / paragraph: c / line: 1, 2)
No, each glider or plane does not require its own flight log. The purpose of a flight log is to keep a continuous record of all flights of the gliders or planes you have built and tested.
(section: 4 / paragraph: l / line: 3-5)
No, the flight time only stops when the glider is no longer supporting its own weight. This can include landing on the floor or getting hung up on any sort of obstacle. Simply touching something does not stop flight time.
(section: 5 / paragraph: d / line: 1)
Not having a flight log is only a 30% deduction in score, it does not effect the tier.
