Action v: Screw and wingnut

[trdd]

Action v:
Rotate a screw to move a wingnut threaded on the screw at least 2 horizontal cm. After moving at least 2 horizontal cm the wingnut must contact and object which initiates the next action.

Similar to last year's Division C but with more specific definition on the screw and the nut.

Would this task be applicable for a timer, or does it have to be something else?

Based on last year's Div. C rules, a timer can be a scorable or non-scorable action, so yes.

With no motor, how much time do you think you can get out of this? I cannot imagine more than 10 seconds.

Is there a rule stopping people from using a normal sand timer of some sort?
When buying screws, buy one with a small number of threads per inch, and as large of a diameter as you can, to minimize the amount of energy needed to rotate the screw.

I don't understand this rule clarification --> https://www.soinc.org/mission-possible

CAN THE WINGNUT HAVE ROTATIONAL MOTION (I.E. THE WINGNUT ROTATES WITH THE ROTATING SCREW) OR MUST IT ONLY HAVE LINEAR MOTION (I.E. THE ROTATING SCREW ONLY PUSHES THE WINGNUT ALONG ITS THREADS)?
The wing nut needs to move linearly. The threaded wing nut must move along a threaded rod or screw.

The wing nut needs to move linearly. The threaded wing nut must move along a threaded rod or screw.

Linear = moving left or right on the threaded rod
Rotational = spinning around on the rod
See here you need another rod to make the wing nut move linearly, instead of spinning around and around on the rod.

But the rule says that the wingnut has to be threaded on the rotating screw and the wingnut has to move 2cm horizontal distance. The rule clarification and the rule seem to be different.

How can a wingnut be threaded on a rotating screw and move only linearly. I can understand the concept behind introducing another object but it seems too complex for division b.

Actually, the wingnut system was how each team's Battery Buggy (a Div B event from last year) stopped. The wingnut will move linearly because the other rod/surface bumping up against a wing of the wingnut will prevent it from spinning around, so it's forced to move along the rod, therefore linearly. The link I posted has a diagram of this.
