We will enforce all clarification of rules issued by ASO. We will also enforce the clarifications by the National Science Olympiad that are issued by February 21, 2015.
Mission Possible B:
4.d.iii Inclined plane….would a zip-line be an inclined plane?
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.
From National FAQ website Does a toy car rolling down a ramp count as a wheel and axle?
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).
There are no clarifications at this time.
