I have another question, sorry if I seem like I'm asking too many of them.

I am concerned that there would be something in the rules that says that one cannot use the ...

How can you claim a gear system is 3:1 if it doesn't do the rotations as expected?

Should the path taken by the golf ball be vertical linear only?

I'm curious how you were able to get this. I thought the distance wouldn't be changed for IMA=2 pullley from IMA=1

Got it! Thank you

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 int...

I don't understand this rule clarification --> https://www.soinc.org/mission-possible (Section: 3 / Paragraph: c / Sub-Paragraph: v / Line: 1) 10/29/2019 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 SC...
