Discussion for the Circular to Linear task.

I'm having a little trouble thinking of a linear motion that would be easy to incorporate. I wouldn't think rolling a ball down a ramp would count, but how about depressing a push-button switch? It's pretty small-scale, but it is linear. What do you think?

I would say that fits the task.

I am wondering, since it says no gears can be used, does that mean you could not use a motor with any gear reduction?

Does a wheel (or a non toothed circle) count as a gear? I don't think so, but just making sure.

For my two cents, I would say yes, gearmotors are out, and no, wheels are not gears.

^ Agreed

Do you think the object has to make a full rotation in order for it to be considered circular, or could it just be headed for a circular motion?

I wouldn't think it would need to make a revolution - any motion around a fixed point would count, IMO.

How about a winch? It seems deceptively simple.

Does a water wheel with spokes that marbles are falling on count as a gear?

If it doesn't mesh with anything else, I don't think it's technically a gear. Definitely submit a clarification, though, since it's pretty gray.
