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: 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.

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.

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.

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.

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: 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: 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.
