Re: Circular to Linear
National FAQ/clarifications do supersede any opinions voiced on here. I don't agree with their ruling and I'm still not sure where gearmotors fall based on that FAQ, but that's how it is.

I feel like this year's mission clarifications were really based on intent.

I also fail to see how banning gears makes this task any different/harder.

Re: Circular to Linear Task
I always assumed that what they were trying to prevent was using a rack and pinion gear setup when they said "no gears" in the rules. But yeah, there are tons of other easy ways to do it.

Re: Circular to Linear Task
I used a small motor that pretty clearly has no gears in it. If I had a crazy event supervisor, I could probably find an identical motor in my box somewhere and crack it open to show that there are no gears inside. But if I were really worried about it, I could change my TSL because I have at least 2 other instances of circular to linear in my device. If you have any mousetraps with string tied to their kill bar, you have a circular to linear right there.
When it comes to the future, there are three kinds of people: those who let it happen, those who make it happen, and those who wonder what happened.

Re: Circular to Linear Task
Sounds like a good idea except mousetraps "don't count as a simple machine" so wouldn't they not count for any tasks (besides the first one, of course)Paradox21 wrote:If you have any mousetraps with string tied to their kill bar, you have a circular to linear right there.

I thought that initially too, but I sent in an FAQ to SOinc and was toldbwy wrote:Sounds like a good idea except mousetraps "don't count as a simple machine" so wouldn't they not count for any tasks (besides the first one, of course)Paradox21 wrote:If you have any mousetraps with string tied to their kill bar, you have a circular to linear right there.
And since the mousetrap in a circular to linear task would behave as a circular motion device, not a simple machine, it should be legit to use for this task.Clarification wrote:No part of a mousetrap can be counted as a simple machine part as indicated
in tasks "b" through "e". For example, a mousetrap can be used in task "b",
but the mousetrap can not count as the "wedge". The 3rd-class lever in task
"e" can not be a mousetrap. Mousetraps can be used for other tasks, but will
not count as simple machines in any task (most importantly for scoring on
tasks b-e).

Re: Circular to Linear
Funny how that works. When I first put "Circular to linear" into the rules, i wrote it as "demonstrate centripetal force". Somewhere between the rules being submitted to the rules being published it got changed to the much watered down "Circular to linear" task it is now.Primate wrote:I feel like this year's mission clarifications were really based on intent.

Re: Circular to Linear
Ohh, that's much more exciting. What were the original parameters for causing the next action? (Did you have to use the centripetal force somehow?)DeltaHat wrote:Funny how that works.

Re: Circular to Linear Task
Ok, so our SciOly team is done this year, but my Physics teacher assigned stuff like Towers, Mousetrap and Mission Possible. **for class
He said for the Circular to linear task, a string attached to a mousetrap wouldn't work because the string still moves up and down.. what say you guys?

Re: Circular to Linear Task
That's what makes it circular to linear. The mousetrap killbar moves in a circular path, and if the string is hanging below the mousetrap, but attached to the killbar, then it will move vertically up and down, which is a linear motion.
