Q: Can I bring a meter stick and/or spring scale?
A: For this event in Illinois, all measuring devices will be provided by the Event Supervisor. Please note, it is important that people follow the instructions in the coaches manual... evidentily this event at the invitational at NSCD contained questions that may be relevant to simple machines but should not be in the scope of the event.

Everyone, My heartfelt apologies I have just discovered the following information at the National Website www.soinc.org/events/missposs/faq.htm

Line 4 Question: Does "counterweight may not be used" mean that the lever must balance or drop on the load side when neither can is added? If so, this might eliminate the use of a lever altogether because one side of the lever will have more mass than the other.

Answer. The rules do not say that the lever itself has to be balanced. If it is a uniform material and is not designed to add additional mechanical advantage due to its thickness or thinness on the opposing ends, the lever arm itself may contribute to the force. Counterweights will not be allowed on either end of the lever to increase/decrease the force.

This interpretation, with which I strongly disagree, makes task completion using a lever much simpler. As a result of this interpretation, as long as a lever is designed according to the above interpretation, we will not be testing to see if it remains horizontal or tilts towards the load side at regionals and state.

Since this ruling comes so late that at regionals, there will not be a penalty if there is a counter weight on the load side... however, at State counterweights on either end will NOT be allowed.

Again, I am terribly sorry if this causes you, or especially, your kids any distress.... I do my best and things like this are a nightmare.

Question about simple machines: If a cart is used to raise a load up an inclined plane ...the cart is not considered part of the load but rather is considered to be part of the machine itself for the purpose of reducing friction.

Response: I've been studying the concepts as I'm about to get the lab ready. If the problem is to raise an object to a certain height without regard to a change in potential energy of parts of the machine, then I agree that the cart shouldn't be considered part of the load. I hope to be very clear on what should be considered when teams are asked to calculate the IMA, AMA, and efficiency.

QUESTION:
One of my students forwarded this email to me and would like an interpretation on it for the state meet. At regionals, he removed the red balloon but it went out of the playing field. No points were awarded. He would like to know how it will be interpreted at state as you can see the national interpretation below.
If the red balloon is removed while the entire robot and box are in bounds, the red balloon points count even if the balloon winds up out of bounds. The only way those points can be lost again is if the red balloon (whole or parts of it) somehow winds up back inside the box or break the plane of the box top or bottom.
Answer: This interpretation is based on a clarification requested in November (below) and that's how I plan to score it at UIUC.

Subject: Fw: Robot Ramble - Div. C
Paragraph: 4 m * 2

Question: Does the robot need to be in bounds during the removal of red balloon, and does red balloon need to remain in bounds once removed?
Answer: Yes, the robot must be inbounds when it removes the red balloon and or deflates the blue balloons. The red balloon does not have to remain inbounds once it is removed. The team earns points immediately for its removal. If it should then go out of bounds, the score is still retained.
